And, I'm sorry but it really looks to me like you'd need a release from
AT&T indicating that any patches you provided to us are unemcumbered by
this license.  I don't see how you can sign away the rights to any
patches that you make if you have been working on code that is covered
by this license.

Specifically, the "YOUR GRANT OF RIGHTS TO AT&T" clause seems to indicate
that they have the right to use your patches if they want them.  That is
understandable but I think that it inviolates your right to assign anything
to us.

I'll stop apologizing for this after this message but I will reiterate
that I don't like this.  I do get asked about this kind of thing all of
the time within and without Red Hat, though.  I don't want to be in a
position of having to say "Uh oh!" to our corporate counsel sometime in
the future.
