My corporate office has IRC blocked, but not instant messaging (like Google Talk). Is there a service that allows me to communicate with an IRC room through Google Talk or another Instant Messaging service?
What I'm envisioning is a website that allows me to register an IM username and tell it to Instant Message that username whenever a new message is posted in a certain IRC room, and when I send an IM from that username to this service, to post that message in an IRC room. Does this exist?
