Over the years for work chat, I've used IRC, Skype, Slack and Hipchat (not to mention outside of work use of some of those, plus ICQ, AIM, Facebook, Meebo, etc). I've had coworkers keep multiple clients open so they can reach everyone -- so having a bridge to connect them could be valuable.

I can see this being especially useful as a support chat for a company or open source project or ... where you have one chat room that can be connected by all the different chat platforms so you don't have multiple places to monitor.
