Zulip has beta-quality integrations for mirroring content with a Jabber or IRC server (also we have one for Zephyr but that's a lot less popular). Check out bots/irc-mirror.py and bots/jabber_mirror.py. It's a bit complicated to setup right now though -- feel free to ping the Zulip development mailing list for help if you're interested.

(Patches welcome!)
