DK is patented too, or am I wrong?

It is patented (which is bad for other reasons, see groklaw.net for much
discussion of the issue), but provides a royalty free license for
implementations of the DK protocol which is compatible with most 
open source licences including GPL.

The senderID patent license, while providing a royalty free license for
binary implementations, forbids source distribution unless the
recipient signs the Microsoft license agreement - making source distributions
so impractical as to be next to impossible.  This effectively kills
any open source implementations of senderID - undoubtedly exactly
what MS had in mind.
