David,

I will note that you could help deal with some of the unknowns if you
could convince your employers to either assert that they believe your
patent covers SRP, or is willing to make a statement that the patent
does not cover SRP.

The current wording:

	This is to advise the IETF that Phoenix Technologies Ltd.
	("Phoenix") has U.S. Patent Number 6,226,383 that may
	relate to the IETF document RFC 2945 titled "The SRP
	Authentication and Key Exchange System".

...is certainly cause of considerible uncertainty.  In fact, some on
the IESG have called it a FUD letter.  (Personally, I believe we
should never attribute to malice what can be attributed to a weaselly
lawyer, but regardless, given such a letter, many people would assume
that it would be necessary to license patents in order to use SRP.)

If you'd like to do your part to get this technology (which you claim
is so wonderful) in wider use, perhaps you could do what you can to
clear up some of the unknowns?
