What's the current licensing situation? I would prefer a copyleft license, but if it already had a free license, I don't really care if it's similar to a BSD license or not.
Edit: Ah, found it:

Wow, this looks awful. It's a vanity license with language that is very unfamiliar to me. Can a license declare something to be legal or not, isn't that for judges to decide, not licenses? It has a bunch of weird clauses that I don't want to try to understand, and Wikipedia claims this is GPL-incompatible and non-free software.
Yuck.
Yeah, ok, I'm kinda interested in a free license now.
