It would have been interesting to hear from some of the SVN-developers
to what extent this could actually become a problem. For instance,
with CVS, I believe that updates can be blocked by commits, but I
would imagine that with SVN that wouldn't have to be the case.

I think one should be a bit careful when selecting the criteria for
dividing projects between repositories. In particular, one should try
to avoid potensially "volatile" criteria like "needs to be accessible
from internet". It is generally a non-trivial problem to reorganize
the project/repository structure.

Are you thinking about anything in particular that can't be
implemented with pre-commit hooks?

I'm not sure what you mean by "impractical for up-to-date checking
purposes", but I think you're putting far too much into the repository
revision numbers.
