If going from GPL -> AL, then it would require that each and every contributor to the GPL codebase would need to certify that they approve a relicensing from GPL to AL. From AL->GPL is "easy" The reverse is hard but do-able (since it requires explicit contributor approval) On Apr 12, 2007, at 11

Thanks, Jim. That's very helpful. I was under the impression that GPL had restrictions that would prevent this, but after reading through the GPL again, I don't see anything that stands out. I guess it'd be the same thing as the original contributor dual licensing the code since there's nothi
