Perhaps there is a segment of the market which will appreciate this protocol 
over NAT, but the problem is that the RSIP gateways require multiple IP 
addresses.  The entire setup smacks of large scale DHCP/dynamic hosting setup 
with an unusual client.  I'm unclear from even a third reading of the RFC as 
to what the real gains are for over NAT - in fact I can point out some 
specific drawbacks.  The protocol is supposed to be implemented at the 
internet address partitioning level, which really means that only large ISP's 
with developing address problems would benefit.
