  Again, I'm reporting what was discussed. I don't think the timing of the
RFCs has much to do with what has been implemented and what has not been
implemented.
  Why was swIPe on the table? I believe that TIS and Raptor have firewalls
out their in the field running it.
  Why was SKIP on the table (and yes, there *is* a pre-IPsec version)? Sun
was there talking about it. They *said* there were two versions that that
the IPsec version was being worked on as they spoke.

  S/WAN is *not* a proposed IETF standard. It is a set of parameters that 
explains how to interoperate *today*. We could have picked swIPe, for instance.

  The 'spec' is says what S/WAN is going to test. I'd call it a "test spec" 
more than a design spec.
  I don't recall discussion about RC4 or RC5 from other than RSA people. But,
again, we were pretty clear about what there interests were.
