Hi Aleksey,
I have not been working on this project since I left my last company, Marin Software -- they were the ones sponsoring me developing it.
I had best intentions of trying to keep up work on it when I left, but in reality, that never eventuated.
I now do a lot of work on the backup infrastructure at Facebook for my day job, so doing similar work on this project in my limited spare time was hard to muster motivation for.
I would be more than happy to hand over the "keys" to the google code repo/project to any individuals interested in hacking on it further.
I'm also going to be around at the Percona Live MySQL Conf in Santa Clara this week if you or anyone else are going to be there and would like to talk about it.
Best Regards,
Lachlan
