Currently Subversion is the only VCM allowed for branching and tagging. I'd like to tag git repo when building has completed. Is there a plugin that will allow me to use git? Is there a release plan for adding git? Is the tagging written as a plugin? If so, is it open source that we could contribute to? Thanks!

Support for other VCSes will be added at some point, but I don't think there's a set date for it yet.

It's a plugin called atlassian-bamboo-plugin-vcs, it comes with Bamboo sources, to which you have access to.. It's likely that you won't need to change the plugin itself (at least not much) - instead, you'll need to make some changes in the git plugin (implement interface TaggingAwareRepository on GitRespository class). Git plugin is open source and located here.
