which dvcs do you use?

git and darcs here.

git for github mainly. but darcs is more simple (on how to manage on my mind)

zip export

The point is that instead of either teaching people how to install a {git, svn, ...} client or manually throwing up {zip files, tarballs} on a web server, I can just point them to
http://example.com/fossil/project/zip/project.zip?uuid=tip and let them download it straight from the repo.

I'm sure some of the fancy web interfaces for other version control systems can do that too, but then you have to set up and configure a web interface -- with Fossil it Just Works.
