Just back from the TeamCity page to questions:
1. maven 2.0.6 is bundled but you can also configure an external one 2.0.4 - 2.0.6. We should
be sure that 2.0.7 works
also because 2.0.6 is quite buggy (probably it will work).
2. It's recommend to use MySQL instead of hsqldb as backend db. I'm not sure if ASF can run
into license problems when
using MySQL instead of hsqldb (which I also wouldn't recommend). This should be check in advance
even when we get
TeamCity as OSS project for free.
3. Do we have some (internal or external) synergies when using TeamCity instead of an ASF

If I can help I'll do.

Yep it sounds like a lot of work is waiting.
