The "mistake" to make over Ireland would be to think that a vote against union with the UK is immediately a vote for a reunited island. A vote in favour of reunion would just be the starting pistol.... and whilst I find it hard to agree with Sinn Féin much of the time, what they are saying is true...... people north and south should be talking about it realistically, not as some "castle in the air" wish. However, you may be sure that the unionists will fight against any such proposal with all the tools at their command.... because, having spent the past 100 years dominating their neighbours, they now find it inconceivable that the situation might change.
Scotland is a different kettle of fish, but the ability of Ireland to stand on its own feet certainly dispels the notion that it would be impossible for Scotland. What is missing, for me, is the passion for independence... it's all words. I don't want to see violence, but I don't see anyone willing to sacrifice their comfort for an independent Scotland, let alone anything more..... so they will struggle with the currency issue amongst other things. The concept of a land border within Britain would also be difficult..... just as it has been in Ireland.
However, there is a greater intransigence by England towards allowing the other nations more autonomy.... I see no likelihood of an extension to devolved powers, so the others will remain as glorified county councils, dancing to the financial tune called by Westminster. This intransigence may well be the root cause of further calls for independence, but it's difficult to see when that balance tips.
Meanwhile, England will continue to have issues with its regional problems and the inequality therein... again, it's hard to see anything but token gestures from a government dominated by people from the South-East and looking to preserve their own advantages.
Just because I'm paranoid, it doesn't mean they're not out to get me
