Meebo is a browser-based IM client that connects to AIM, ICQ, MSN, Yahoo, Jabber, and Google Talk IM networks. If your employer has locked out all connections excluding those on port 80 (default web traffic port) you can use Meebo to get online when the normal IM applications won't work. This type of blocking is usually accomplished using a firewall, but Meebo allows you to get around it.
Meebo is still in alpha, so it's a very early version that is basically still being tested. It may not be the smoothest solution out there, but if you're looking to IM and can't use the usual routes on your computer Meebo will get the job done.
