SRP would be useful to have.  However, as it is patented I do not know
if it can be included in OpenSSH.  The grant in the patent seems to
place restrictions on the licensee.

It is not clear if EKE or SPEKE patents are required for a SRP

As far as I see it, everything that is patented is tainted.
Somebody who has money to pay a lawer needs to investigate
this further.
