Yes. I would like to add my current rmap optimization work, if it is worthy
for the usual reasons, to the kernel under a DPL license which is in every
respect the GPL, except that it adds one additional restriction along the
lines:

"If you enforce a patent against a user of this code, or you have a
beneficial relationship with someone who does, then your licence to
use or distribute this code is automatically terminated"

with more language to extend the protection to the aggregate work, and to
specify that we are talking about enforcement of patents concerned with any
part of the aggregate work. Would something like that fly?

In other words, use copyright law as a lever against patent law.

This would tend to provide protection against 'our friends', who on the one
hand, depend on Linux in their businesses, and on the other hand, do seem to
be holding large portfolios of equivalently stupid patents.

As far as protection against those who would have no intention or need to use
the aggregate work anyway, that's an entirely separate question. Frankly, I
enjoy the sport of undermining a patent much more when it is held by someone
who is not a friend.
