I've had good success with subgit in getting git and svn repos to always
stay two way mirrors of one another. See
https://github.com/ned14/boost-trunk 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
commit.

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.
