Which of these result in incompatible changes with 3.0.*?

So you are proposing to autogenerate more IDL interfaces than just DFS?

By "sweeping", do you mean "incompatible" or just "large"? I would say
that incompatible changes could be a good rationale for bumping the
minor version, but would have to be convinced otherwise.
In general, I strongly support anything that moves the Samba3 and Samba4

Sounds like a good thing.

Frankly, I don't know whether SGI would ship a 3.0 release and a 3.2
release on IRIX/Origin. I can't speak for SuSE, but this would certainly
complicate my life supporting Samba on SLES/Altix if SuSE chose to ship
3.0 and 3.2 versions.

Given we already have less testing coverage than we would like,
splitting our user community into 3.0 and 3.2 is a difficult decision.
For how long would we support 3.0.*?

I don't see any problem in changing behaviours radically within the 3.0
series, provided it is done in a compatible way. If this is not
possible, then I'll come around to the 3.2 view.
