I've been tossing around the idea of adding a c['extra_services']
variable to master_cfg.py, which the buildmaster would start at
application startup.  I don't have the patch handy, but it sounds like
your question would fit easily into that.

In the interim, it's probably easiest to just set up your class as a
service and instantiate it directly from the BuildMaster's
constructor, similar to the way self.botmaster is set up.

I'll try to get that patch in a bit.  I've made a terrible mess of my
darcs repos at the moment :(
