Of course I also hope there will be some reforms in taxes and bureaucracy to make starting a business in Scotland a reasonable proposition; currently it's not rational to start a tech business in Scotland, given the immense advantages of doing business in the US. I don't have much confidence that Scotland will actually become more business-friendly, but it would definitely be more likely as an independent nation.
But, yes, if an independent Scotland did create a business climate friendly to entrepreneurs and did make it easier for tech people to emigrate from the US, I for one would make the move in a heartbeat.
