This is what I wrote to my SourceForge account about the development of phpAIM (AIM is (tm) AOL).
Unfortunately, development has stalled before it really started. I was originally going to design a PHP script that modeled the Perl Net::AOLIM module, but I think I'd rather write an extension that uses the libfaim (http://sourceforge.net/projects/libfaim) and create a real PHP extension using it. If anyone would like to contribute, please write.
