bazaar-vcs – alternative when sf.net cvs/subversion servers are down

Just when I was just starting to get comfortable with svn, along comes bzr.

svn has a lot of benefits over cvs. For me, the biggest benefit is the increased ability to work on a plane I can do an svn delete or an svn diff while disconnected. When I land, I can simply do an svn update and an svn commit.

It looks like bzr intends to take this to the next level, I can work on multiple changes, create branches, and query the version history while offline.
[ED: it might be useful when sf.net cvs/subversion servers are down, I think of it as an p2p scm]
