In search of a “universal IM client”

BronwenWeeGo.jpgI now face the problem of contact on 4 different instant messenger clients….MSN Messenger, Google Talk, Skype and now ICQ (for my new job).  I started looking at Meebo which allows me to log into 3 of the 4 at once without having to install yet another client and it’s looking ok so far.  Least it means i don’t have to install and run 3 separate IM clients. 

So just wondering the following:

What does everyone else use?

Anyone found one that does all 4 clients?
