I could help you out if you need help in bzr.
By the way, do you have any experience with git or Mercurial or bzr? (I have very little experience with any VCSs outside of Subversion, and a bit of CVS.) If someone else were to help me with xuni, it would probably have to use a distributed version control system instead of SVN. The main reason for this is that I'm using a local SVN repository as the "master" one that I commit to and everything, because I so rarely get online. I then replace the SVN repository on Sourceforge with mine whenever I get around to it. So this wouldn't work very well with multiple developers.
