I'm opposed to Mercurial unless you're willing to write a portable
implementation in C or Bourne shell + POSIX utils. I don't have Python
and it's not terribly portable... Last time I tried to build it I
remember it being hell...

Also, FWIW, I'd strongly prefer systems that can be used fully online,
without having to keep a full local copy of the repo. I often use
machines that don't have hundreds of megabytes (or worse) of space
free for a local copy of the repo... both old machines and shells with
limited quotas. CVS->SVN already made my source trees grow 2x and I'd
rather not have them grow 100x on top of that...
