"But the license has been granted from IBM to Apache, not to us."
Well, kind of. Part of that license is a grant of permissions to anyone to whom that software is distributed by Apache. The question is what the precise meaning of "distribute" is in this case - we've already had an assertion that the code in question hasn't been published by Apache. In any case, Rob's right that this isn't the right venue for an authoritative answer, and so I've mailed the appropriate mailing list.
