<p>just picked this up <ahref="http://gigaom.com/2005/09/14/ajax-based-im-meebo/">via Om</a>:</p>
<blockquote>
Through Ajax, the folks at meebo were able to create a virtual application-like experience within a single web browsing window. meebo integrates a user’s accounts from AIM, Yahoo Messenger, MSN Messenger, and ICQ into a single buddy list that is automatically populated upon signing into the meebo web site. Sort of like Trillian/Adium, but in a browser window.

<p><strong>UPDATE:</strong> I just noticed over on the <ahref="http://blog.meebo.com/?p=13">meebo blog</a> that they're using <ahref="http://gaim.sf.net/">GAIM</a> (libgaim, I presume) to connect to the IM networks:</p>
<blockquote>We use Apache and Linux (CentOS) on the servers, and connect to the networks through Gaim</blockquote>
