If you have all your online friends scattered across different IM networks, you need an IM client like Meebone.

With Meebone you can connect to multiple IM networks simultaneously, giving you the chance then to chat with your friends from Jabber, Meebo, MSN, AIM, Yahoo!, ICQ and Google Talk at the same time.

When you run Meebone you'll be asked to login to any of the supported networks. Then, if you want to join another network at the same time, click on the "Sign on" button at the bottom of the program's interface.

Meebone is actually an Adobe AIR desktop port of an online cross-platform IM client named Meebo. Maybe this is why its interface is not perfect yet and has some glitches, but we have to bear in mind that the program is still at a beta stage.

Meebone lets you chat with your online friends at any moment, no matter what IM network they use. The program is still in development though.
