It doesn't seem like it's super active right now, esp. since more and more HTC phones are coming with Android. And even when there is a port it's usually a bit unstable, and not really something I'd rely on for my primary device. You're better off waiting for HTC to come out with a similarly spec'd phone running Android. It'll happen eventually!
Doesn't appear to be anything stable/fully functional yet, but give it time, she's a brand new platform.
The XDA Developer's forum is the best place I've found for HTC related ROM development.
