My instinct is that if there's a YES vote, all the stuff about England not playing ball in setting up a shared currency deal, or about problems in Scotland being in the EU will mysteriously melt away.

So far as the latter matter is concerned I'm still puzzled why it is that there is said to be a problem with Scotland staying in the EU after independence, but not for the other part of the former UNited Kingdom (of Great Britain and Northern Ireland), whatever it may choose to call itself. Two new countries.
