Thanks again for the info, Alex. If NI does indeed allow both licensed and non-licensed versions then that would seem to be the best of both worlds, why does (almost) nobody do it?
Oh, and please try to maintain K4 compatibility (which you'll lose if you license with NI) for those of us who are trying to get off the NI merry-go-round of annually repurchasing the same sampler over and over again.
