RE: protocol progress...

Tom,

> Stanford's royalty-free IPR statement is on file with the IETF. 

True, and that is much appreciated, but ... 

.. has any company/organization other than Stanford make IPR claims
about SRP? If so, what are those claims, how valid are they, and are any
of those making the claims NOT prepared to offer royalty-free IPR on
them?

If the technically excellent SRP were totally free from royalty-bearing
IPR claims, I would be happy to see it used, otherwise a different
solution is needed.
