Fears over post referendum relations

Have you noticed an escalation in the edge in pronouncements about the forthcoming Scottish  referendum on Sovereignty? Arguments, counter arguments and threats are becoming more desperate as the day approaches. For some the stakes are very high indeed and I fear that things said now, especially about the use of the Pound Sterling, may have a deleterious bearing on Scottish relations with England in the aftermath. As the rhetoric rises, urged on by the fervent Nationalistic interests, will the flames of debate lead to a conflagration of conflict?
As an aside, who is paying for this charade? Since Mr. Salmond, increasingly adopting the mantle of Robert the Bruce, has made it clear that only the Scottish people can have a say on the state of the union, are the costs being borne by those north of the border only? I somehow doubt it.
