Now that CIA is dead I wrote a new Roundup detector that uses irker
[0][1] instead of CIA.  It requires the irc package [2] and the irker
daemon running in background.
It's also necessary to add 
  [irker]
  channels = irc://chat.freenode.net/channelname
to detectors/config.ini to make it work.

We have been using this on bugs.python.org for a while and it seems to
work fine [3].
