[gameprogrammer] Re: GPL Questions

It appears to be valid to release two versions of a license for the exact
same product.  In the case of Raknet, it appears that it can't harm me
because the freeware version is already open source and freely
distributable.  However, GPL users can't use it because the GPL license is
more restrictive than mine.

I'll go ahead and do that then.  If it turns out I'm wrong according to the
GPL I can't retract that but I have few enough users I doubt it would
matter.
