Of course, but I imagine you'd have to define your own poller.

I have a vague memory that, based on their checkin comments, I figured
the chrome folks are doing this.  Their BB configs are available in
their public svn repo:

  http://src.chromium.org/viewvc/chrome/trunk/tools/buildbot/

I expect it would be more work to figure out how they do it than to
just do it, though.  I would bet a quicker route would be to look at
the pydoc for p4poller and/or its parent classes, and see if there's a
method you can override in a derived class.
