It makes it easier to dance around real or perceived IP issues, and thus I can likely more successfully "push upward" as you put it.

I could end up with one of these... :)
At this time, I don't think that is going to happen, but I would like to see it regardless.

Honestly, I fail to see where you think there is a derivative work, so, I'm not really sure what discussions I need to revisit with our lawyers.
