AFAIK the Apache license (without the additional paperwork assignment)
only grants the Apache foundation the same rights as anyone else, i.e.
to use the code under the terms of the license. The Apache license
is not restrictive (at least not in the same ways as David was proposing),
so what it does not do (as far as I can tell) is allow the Apache Foundation
to license modifications under different terms (for instance a proprietary
license). I'm doing this from memory and from your quote above without
going back and checking, so do correct me if I'm wrong.
