I tried it out on a little local SVN repo recently, and it worked just fine. It delivered pretty much perfect two-way syncing/bi-directional mirror (which I've earlier deemed to be very impractical with git-svn).
The bad parts are:
- It's new (use at your own risk, in other words: DO NOT install it in your main-line subversion repo used by a 100 devs).
- It's closed source, so you're at the mercy of the SubGit devs for fixing any feature that you need in your special repository.
- It requires instrumentation on the Subversion repository installation. If the repository is beyond your control (hosted externally, or by some separate department), you're stuck with my old setup.
The good parts:
- Super-sweet functionality! I mean, bi-directional Git/SVN is highly sought after.
- Seems to have a pretty high *just-works* factor, easy setup.
- It's still free (as long as they're in the EAP phase)
