And here's the other thing
In the event of independence, and given the current fragile state of our economic recovery, it would be political suicide for any party to give an inch to Scotland, especially given that we have a General Election next May.
Things that you say if you never want to be elected again in the rUK:
"Yeah, we'll leave those shipbuilding jobs in Glasgow in that foreign country, and not move them to Portsmouth or Newcastle"
"Yeah, we'll not bother employing 5,000 people in an impoverished part of the North, we'll outsource that work to Scotland"
...and so on
In both of these cases in particular, and in the whole independence thing in general. I think that any contractual hurdles will be legislated out of existence.
