I recently upgraded both [NetMRG]'s and my own CVS repositories into subversion repositories. Everything seemed to go pretty smoothly. I setup ssh access for developers, and have both the webdav stuff setup for anonymous checkouts and the new ViewCVS setup for tree browsing. The only thing I recommend is that you use the 'fsfs' backend type so you don't need to give the Apache process write access to the repository.
I also built RPMs for FC3 for several packages that I didn't have. Mostly packages that I install on my servers that I haven't upgraded yet, but nice to have nonetheless. Feel free to let me know if there's a package you'd like updated to a newer version. I typically only update when I need to myself.
