Actually, there is a third option:
The "real" repository lives on some specific machine, either in the local
filesystem or in AFS. Everyone with authority to make changes to the
repository has ssh access to that machine. Whenever a change is made, it
is automatically propagated to a read-only "public" repository (immediately
by a hook script, or on a periodic basis by a cron job, or simply by having
the "real" repository world-readable in AFS).
This approach limits the scalability problem to the set of people who are
authorized to make changes to the repository. The problem should be
manageable on that set, since if it is too large than you have bigger
problems than having to manage accounts on the repository machine.
