I'm thinking of something like this:

	If the copyright holder of this package has granted permission
	to anyone to redistribute it under the copyright laws on any
	terms other than these, or by any instrument other than this
	license, then this permission is void, and you have no right
	under this license to distribute the software.

In other words, a license could get so offended when an author
dual-licensed some code that it cancels itself. :-)

So it should be possible to have a license which is resistent to use
in dual licensing situations.  The author of the licensed code wouldn't
be prohibited from granting the permissions; instead, one of the
permission grants, by its own terms, might be inoperative.
