I guess what I'm very much worried about is that there is
potentially-infringing code there, we know about it, and we may press
ahead and release with it anyway.  IBM would justifiably jump on us
for that as a result.  What I simply don't know is what they can

enough, fine.  But given how widely the code base will be
disseminated, I'm worried they might demand that we somehow track it
down and get rid of it.  That would be a significant distraction, I

First, that's hardly a justification, and second, they're not all
subject to inspection.  Plus, this is a case where we _know_ about
the potential violation, and have had it pointed out to us, before
the code has been declared "released".
