I've had good success with subgit in getting git and svn repos to always
stay two way mirrors of one another. See for an example, though I've disabled
the git to svn mirror there as all commits to github would appear under
ned14 in svn because I never bothered with configuring the two way map.

Note that subgit needs about 250Mb of RAM, sustained. It also introduces a
certain amount of lag to both git and svn commits in order to duplicate the

As a temporary measure until we can drop svn forever, it's doable. Note that
subgit can be configured to handle a modularized, decentralized git or svn
structure, but that is probably significant work as you won't be able to
reuse much of the existing scripts.
