BitlBee

 BitlBee  is a communication gateway from IRC to other chat.

BitlBee natively supports the following IM networks/protocols:
 * XMPP/Jabber (including Google Talk)
 * Microsoft MSN Messenger
 * Yahoo! Messenger
 * AOL AIM
 * ICQ
 * Twitter API
 * plus all other Twitter API compatible services like
 * identi.ca
 * status.net
 * HipChat

It can also be built to support libpurple ( the library Pidgin uses ) to extend it's protocol support. There are also 3rd party additional modules for libpurple.

Ideas

 * Set up a Bitlbee to micropub protocol and you could post notes directly from chat. —
 * Webmention notifications in bitlbee might be easy to set up, but maybe just direct IRC would be easier.
