Was that not answered in my previous e-mail (quoted below)? Although as 
you pointed out, I seem to have defined things in such a way that we 
*can* define what an "ISCMParameter" is in a generic way that doesn't 
need to be a black box.

Right... except, why just one? :-) Certainly I would assume branching 
can handle many (you might have to do them one at a time, but that's a 
back-end detail), and you can check out several things, again one at a 
time. Doesn't svn even figure out how to correctly do an update when you 
do this? (e.g. the admin directory we have in 3.x?) Or am I imagining that?

You mean that each item in the QMap has a flag, yes? :-) Hmm... maybe 
that works, although I don't see why you wouldn't just use a list. 
Anyway, this should I think be fine for both perforce and svn, at least. 
What about other VCS's?
