At one time, I think the RSAREF license was stated in such a way as to
expressly prohibit any use of RSA, Diffie/Hellman, and other RSADSI owned
technologies where data was transfered for revenue generating purposes.
While I think the current license on RSAREF v2.0 is far more permissive
(I glanced at it today), I believe the previous language meant virtually
any business use where data was communicated infringed on the patents.
I can dig out the previous language if you're curious. Still, I'd be
very worried about using this until our lawyers gave me the all clear.

Even in this instance, one could write a trusted third party system. Ker-
beros is one example. At one time I had planned one using Newman/Stubble-
bine protocol and Blowfish, but our talks with the client deteriorated
before I got the beast designed. Basically, they wanted us to in effect
subsidize a T1 for their use. There was no money there for service let
alone cryptology R & D.
