Unfortunately the revision numbers are repository/working copy
specific. The central server could very well have a different revision
order than your local one.

Furthermore, I would like to add that this should be a discussion
about which development model we want to have. If we want to stick to
the centralized repository model then subversion really does almost
everything we want. If we want to start experimenting with a less
centralized model (for example with lieutenants), then there are other
options.
The choice for an alternative RCS really should depend on requirements
we have, not on tastes.

I would like to extend the test suite a little bit more, to test some
more complex configurations. If I did that I will share the source on
http://hg.haiku-os.org. It basically is a hook that responds to hg
push actions. I will write a short blog explaining the theory behind
it.
