Update: There's now a Xing signup for the event: https://www.xing.com/events/living-with-git-and-subversion-parallel-710010
I will be heading up to Essen next month to present Git+SVN at the ruhrjug event. The arrangers (Infaktum) are also behind GearConf, where I presented on the same topic last year.
The event takes place on 14th of April, and starts at 18:00 in the Glaspavillon Campus Essen:

If you want to know the tricks of living with Git and Subversion in parallel, be there!
I'll be showing off all the steps, from getting started with git-svn, through the obligatory Git-Subversion mirror, to the final-migration-away-from-SVN. Hopefully there'll be time for showing off stuff I didn't get to at GearConf, as well as some good discussion.
Oh, by the way, if you've got any reference cases where you are also using git-svn, I would love to hear about it. I recently noticed that Gnu Cash are using it, and it would make me happy to hear if others have had success with it (or if you had troubles, drop by the Git-for-human-beings mailing list and ask there).
