Interesting discussion.
We appreciate the concern, to be sure. If anyone wants to take it upon themselves to try to curtail piracy of our software, or any other, that's a noble endeavor. But I think it's safe to say we're not too worried about piracy. We provide a completely free version of our software, and the key system while not terribly sophisticated, is at least a much smaller target than Maya and other well-known software.
I do occasionally look around for a working cracked version of TG2 (TG 0.9 was cracked a long time ago), but I have yet to find one, so it's interesting that Dublin seems to have. As someone mentioned, if we had the key it uses we ought to be able to determine who it's from, unless someone managed to create a working gey generator...
