Speaking as an Debian OpenMPI maintainer, I as well endorse a switch away from
SVN since it will make package maintainance more easy for us. Most Debian
maintainers tend to use git (if they use a DVCS), Ubuntu seems to prefer bzr,
but I can't say about others. Of course, you should use the systems you
prefer but it may be worth to consider the preferences of distributors.
Debian has quite sophisticated tools for packaging for almost all DVCS, so it
is not really an issue which one you'll choose from Debian's point of view.
(I personally prefer git over all others. I'm a git fan-boy. Don't know
Dirk's opinion on that.) I use git for my packaging work on OpenMPI, although
we have a SVN repo. ;)

Anyway, switching away from SVN would ease the work on both sides, since
patches/commits can easily merged between our repositories. Features like
cherry-picking can be very useful here. Also, git's feature to export/import
commits via email helps a lot, as I can tell from experience. Reducing the
time to integrate changes/patches is definately worth switching to an DVCS.
