It appears that a guy named Ruben Unteregger published the source code on his site at http://www.megapanzer.com/source-code/#skypetrojan
According to his site, he removed a plugin system from the source as well as code to bypass firewalls, but he'll add it back in at a later date.
From looking at the source, this is heavily geared toward Windows, so the current iteration of the source doesn't affect OS X at this time.
I'm sorry, but after the abomination that was Hellgate: London, it will take a very, very long time for Bill Roper to earn my trust again. That game was a prime example of what NOT to do in an MMORPG. I just feel bad for all the people who blew their money on a "lifetime" subscription which ended basically being an extended beta masquerading as a finished game, full of broken promises, missed release dates, glitchy content, and eventually a slow death. I hope he's learned his lesson, but I'll let other people test the water before I'd be willing to jump in; I'm not ready to get burned by Roper again.
That entire series is excellent, but having read all of the books in the series that have been published up to this point makes the wait until next fall for a new hard! Be sure to read the other series that starts with Island in the Sea of Time by S.M. Stirling as it ties in with the event in Dies the Fire.
All power corrupts, but we need electricity.
