That sounds great.  Do you have a ViewCVS link?

The one feature that we'd need beyond the simple "wake me up when 
something is ready" interface is the trigger interface.  It lets a 
thread tell the main thread to wake up immediately.  I'm pretty sure 
Twisted includes this, but I don't remember where.
