Not being an economist I'm not sure about keeping the pound but I don't see the problem with an open
border. There is one already with the Republic of Ireland.
I didn't know about that (border) and having looked further, I can see that's what the SNP are hoping for. Though someone might throw in a small spanner for this one. There is one area which could cloud this situation - the Schengen Agreement.
It is a common travel area which numerous European countries are signed up to - but not the UK and Ireland.
Regarding the EU, I found this on the beeb:-
4) Will Scotland be a member of the European Union?
The SNP is in no doubt that Scotland would be part of the European Union after independence.
It says: "Scotland is part of the territory of the EU and Scots are EU citizens - there is no provision for either of these circumstances to change upon independence."

The 2009 white paper says: "Settling details of European Union membership would take place in parallel to independence negotiations with the United Kingdom government and would cover areas such as the number of MEPs and weight of Council of Ministers."
However, a document produced by the House of Commons library said there was "no precedent" for a devolved part of an EU member state becoming independent and having to determine its membership of the EU as a separate entity.
It said the question had "given rise to widely different views".
A spokesman for First Minister Alex Salmond has previously said: "Legal, constitutional and European experts have all confirmed that an independent Scotland would continue in EU membership.
"And how could it be otherwise, when Scotland has the lion's share of the EU's energy reserves, including oil and renewables?
"The fact is that the last major EU expansion in 2004 saw 10 new countries join - six of them smaller than Scotland, and six of which have become independent since 1990."
In May 2012, Deputy First Minister Nicola Sturgeon told a BBC debate that an independent Scotland would automatically gain EU membership, but did not need to use the euro.
Scottish Tory leader Ruth Davidson produced a letter from the European Commission that she said showed the SNP had never asked it what status an independent Scotland would have.
Ms Davidson said: "The fundamental question that the SNP haven't answered when it comes to Europe is that they don't accept, or won't admit, that a separate Scottish state would have to apply to join the EU.
"One of the rules for applying to join the EU is that you have to adopt the euro. That is the law, so it may not be within the choice of an independent Scotland."
Owen Kelly, chief executive of Scottish Financial Enterprise, said: "Nobody actually is arguing that Scotland would not be a member and I have certainty picked up no vibe in Brussels that there would be anything other than acceptance of that."
He said the real question was on the terms of joining.
Mr Kelly said: "If an independent Scotland would simply inherit all the UK's obligations, opt-outs, international treaties and everything else, fine.
"But if it doesn't, if that is not what is going to happen, then we really need to know because you are then looking at a period of accession and a period of negotiation."
He said: "If we had the political will I think we could find that out now. We know the terms of the referendum and the timing, what else do we need to know before asking and answering that question?
Then someone asked a question about pensions, that was interesting reading too:-
5) What would happen to state pensions?
Your Scotland, Your Voice says: "On independence benefits, tax credits and the state pension would continue to be paid as now in an independent Scotland. It would be for future Scottish administrations to deliver improvements to the system designed for Scottish needs."
An SNP spokesman said: "People would get their full pension entitlement from day one of an independent Scotland, that is the government's guarantee.
"National insurance would continue to be paid in line with the current arrangements.
"There are EU rules in place to regulate the payment of pensions in different countries and these would, of course, be followed."
Pensions expert Malcolm McLean, from consultants Barnett-Waddingham, said: "The devil is in the detail of pensions. It's not as simple as it sounds."
He said a change of currency would cause "all sorts of problems" for the division of pension liabilities between Scotland and the rest of the UK. However, Scotland intends to continue using the pound Sterling so that difficulty may be avoided.
Mr McLean said he thought people drawing their state pension at the time of independence, if it happened, would notice little difference, especially if Scotland was an EU member.
He says: "Existing pensioners would probably be treated as overseas pensioners in the same way as UK pensioners living in other EU countries are."
The difficulties, according to Mr McLean, would come with people who have been paying national insurance contributions to the UK treasury.
He said the social security system was based on national insurance contributions, with the details held on a computer in Newcastle.
Mr McLean asked, would the Scottish government set up an equivalent database for Scotland, or would the Newcastle system be used as a base for all UK and Scottish pensions after independence?
Then there is the issue of "accrued" rights, he says, and how they would be transferred from the UK to Scotland and who would be responsible for paying the pensions.
A big problem with state pensions is that they are "unfunded", said Mr McLean.
Despite taking in the money in national insurance contributions, the pensions are paid on a pay-as-you-go basis straight out of the Treasury.
There is no state pension pot to draw on or divide up between the rest of the UK and Scotland, states the pensions expert, who argues the question of pension liabilities is a huge one which still has to be addressed.
On the issue of private pensions, Mr McLean says - although a currency union may remain - the different tax regimes in Scotland and the rest of the UK would be extra complication and cost for pension providers.
Dr Jim McCormick, of the Joseph Rowntree Foundation, thinks the division of state pension schemes is something which needs to be done "with caution".
He said it was "certainly not something you can do quickly or neatly", arguing that one way forward could be operating different pension pots for pension liabilities from the UK before independence and Scotland afterwards.
He added: "It would make perfect sense for an independent Scottish government to do some cost-sharing with a UK government for people close to the state retirement age. They could gradually move others to a new system. They would want to move with a lot of caution and partnership."
