We can make commit rights as specific as we want, by hacking on the
repository code (I assume we'll start with SqueakSource as a base). 
But I would probably incline towards either giving someone full access
to the release repo or not.  If they're working on something pretty
core to Squeak, they should probably be allowed to use their judgement
about committing versions of packages they don't technically maintain
(like a modification to Kernel requiring some change to Collections or
something).  If they're working on something more external, they
should just commit to their own repository and have some release
manager copy specific versions into the release repo.  I think that's
more or less what you say later in your message anyway, just trying to
get my own thoughts clear.

I'm not really sure what you mean by "no merging to worry about
later".  It's perfectly possible, for example, to maintain multiple
branches in multiple repositories and be constantly merging between
them.  Or to have the same versions mirrored across multiple
repositories.  Or to have some versions in a particular branch in one
repository, and some in another, etc.  It's probably best in this
context to think of repositories more like tags: putting something in
the release repository means you're tagging it as "releasable".  But
it might have been a version that you originally committed to an
internal development repository and copied over.  Monticello is much
more flexible than CVS for that kind of thing because each version
carries with it all the ancestry metadata it needs, and a repository
is just a collection of individual versions + access rights.  Does
that clarify things somewhat?

Well, let's get a repository set up and see how it goes.  What's the
current status of the server?  Does it have the
capacity for an instance of SqueakSource for this, or should we find
somewhere else to host it for now?  Bert, I know you guys have made
some mods to SqueakSource as well, would it be easy enough for us to
make a fresh copy of your setup and deploy that?
