everyone--

My question about the architectural model of Dave Thaler's SAF being related to Realm-specific IP was not an idle one. It's a rare enough occasion that I'm the one who remembers something relevant that someone like Dave doesn't already know about, that I'm genuinely surprised when it happens. Hence, my hair pulling. Sorry about that. (I was also over-caffeinated. Sorry about that, too. I was awake until 0300 last night fixing bugs.)

Realm-specific IP is described in RFC 3102 and RFC 3103. The protocol was even defined to support both IPv6 and IPv4 address realms on either [or both] sides of an RSIP gateway.

        Framework:               <http://tools.ietf.org/html/rfc3102>
        Protocol Specification:  <http://tools.ietf.org/html/rfc3103>

It strikes me that if SAF isn't equivalent to RSIP, then I'm not seeing the relevant distinctions. Also, if SAF *is* functionally equivalent to RSIP, then what makes SAF now more architecturally appropriate than RSIP was then? If SAF isn't equivalent to RSIP, then what's the difference I'm missing?
