Not a flippin snowball's chance in hell
The Xith stuff is awful.
Personally, I'd say it's unlikely *whilst we are still actively developing the game*. I'd also guess that it's pretty likely we would decide to OS it *if* we stopped actively developing it. But those are just guesses - I cannot speak for the others thoughts and opinions.
And I'm anti-open-source by default (although I do run a project on sourceforge.net, so it's not like I *won't* open-source stuff; just my default assumption is that I won't). Deciding to OS something is a major decision, one which only the rich, the idle, and those who don't care about the future of their project can make flippantly. If we were to do it, it would only be after very serious consideration and examining it from all sides.
