Given the would be 'King' of Scotland has determined that he will keep all that he wants - such as the £ and HM - and only reject that which fails to meet his cause, it is hardly surprising that he expects everyone else to dance to his tune. As was said by a Scottish ex-pat friend recently, when Scotland finds that half the industry and financial concerns leave as a result of security and EU rules, unemployment rockets, and there is no right for its citizens to migrate within the EU then the penny will drop - of course that will be after the horse has bolted.
Regardless of what Junker says, I believe that any new country that wants to join the EU must be voted in by current members. Given that Spain has a problem with the Basques wanting independence (and other countries also have similar problems) is it likely they will vote for Scotland knowing it could easily make their problems worse - I feel it to be unlikely.
Those suggesting that the SNP will cease to exist if Scotland votes for independence are falling for a Salmond trick. Salmond is aware that he isn't universally popular and this suggestion that he would disappear (and his party) is so improbable that it is almost laughable. It is the Scottish National Party, not Scottish Independence Party.
SNP will NOT disappear on independence being voted for. Why would they? They aren't a single issue party like UKIP. They do actually have political views aside from independence broadly similar to the Labour party which is how they have gained support as Labour in England took a lurch to the right. Working class people have therefore been attracted to the SNP.
SNP and Alex Salmond will still be wanting government and power after 2014.
