@insto, I think that's overly cycnical, and it suggests to me that you're not very familiar with the attitudes of SNP activists.
All the activists I know - and it's a lot - are really enjoying working with the "rainbow coalition of Trots and Greens". I and other SNP members put out a leaflet for Green Yes on Sunday, which includes a section on how to join the Scottish Green Party.
The activists are very idealistic. They genuinely believe in in the Yes movement and take pride in its breadth. If the SNP's leadership were p*ssing off the wider movement, the SNP activists would loudly support their new compadres.
Also, again speaking about the activists I know, they don't have much loyalty to the the SNP as a party. Over the last 3 years there have been regular discussions about what we'll do after indy, and about a quarter of the members I know have said they'll join the greens or the trots. A few would join Labour if it stopped being so stupid and grew up. I suspect in practice they'd work to get an SNP government for the first term, to get the institutions of government bedded in, but after that I can't see how the SNP could remain the biggest party.
At the 2011 election party - in which people were walking around in a giddy daze, asking everyone if they'd got elected to someone - there was aloads of talk that this was just the presursor to the main event - the referendum. Because the SNP emphatically does not exist to form governments. It exists to win independence, and everything else is designed to achieve that.
In practice I don't see any way they could trust someone like Darling to negotiate for independence. But
Oh, and the vast bulk of transition and negotiations are administrative things that are small potatoes and will be handled by the civil service. It's only on the big issues like currency, Trident, armed forces etc that wider voices will be needed.
