It is alive! CodePlex has Subversion Access
It is so much fun to see things that I worked on coming alive. The official announcement is here, with all the boring details. You can skip all of that and go read the code directly using SVN by hitting: https://svnbridge.svn.codeplex.com/svn
Switch svnbridge for your project, and you are done. Note that this is https. And yes, it should work with git-svn as well.
