There is a big benefit to having a standardized, vetted license ready
to go. Today, if a patent holder wanted to do a 'good deed' and put
thier patent out under a GPL-supporting license, they'd be up against
a huge expense, never mind the problem of 'designing' a license that
did what they wanted. The legal fees of drafting something new
and completely custom like this are enormous. Having a standard
document removes this barrier.

The docterine of 'mutual assured destruction' is what drives companies
to cross-license each-others patents.
Suppose I, as an individual held one patent, and I implemented it in
gnome-foo. But suppose gnome-foo also infringed on one patent from
small-company X. Suppose that small-company X in turn infringed upon
my patent. Then, if they attack, I can bargain and cross-license
my patent. Right? Standard stuff.
Now suppose that "my patent" wasn't something I personally invented;
rather it was something I'd acquired rights to somehow, e.g. by
purchasing it from the original inventor. Then te above defensive
tactic still works.
See where I'm trying to go?
Now suppose that I'd acquired the rights to "my patent" not by
purchase, but through a contract/license from RedHat. Oh, by
the way, RedHat has licensed this patent to all GPL'ed software
developers; but that, I hope, is immaterial. I, as the author
of gnome-foo, suffer damages when Company X infringes on "my patent".
(I am suffering because gnome-foo no looses has a competitive
advantage over company X's product when X infringes on "my patent".)
There is one catch with the above scenario, and its a big one:
the defense works only if company X is infringing on "my patent",
as implemented in gnome-foo. The fact that company X is probably
infringing on *some* GPL'ed patent is not enough to save me; I can't
threaten them with these other infringements because I'm not damaged
by them (right?).
If the above theory is good, then it would seem to be able
to defend the bigger, more complex GPL'ed projects against the bigger
companies with bigger portfolios (since the likelyhood of mutual
infringement is that much higher).

The trick is to stock the pool with patents that haven't been
widelt cross-licensed.

If IBM relicensed thier patents to me, then they wouldn't have to
pro-bono anything; I'd go begging to EFF or something for that.
I need a license that effectively lets IBM's patents be "my patents"
so that I can go defend them.

Bing. And, for that, we need a well-known, well-understood "famous"
license that small companies can use.

Yeah, this is the tricky part, which is why I proposed the above.
This is the part that needs some good creative energy ...
