Greg (?),

You are making assumptions that a willing 4.x is available to front the
application and that a front-end protocol will be designed for it (them).
I prefer not to need that horsepower and use IP directly over the
micro-IMP (or whatever) link, even if encapsulated in SLIP, hello or
other suitable envelope. Address management and authentication is an
interesting issue - see for example the schemes used by the fuzzballs
(RFC-891) and (a different one) the MIT PC/IP gateway. For authentication
I offer a variant of the Needham-Schroeder scheme (e.g. RFC-1004). My
point is that we shouldn't have to climb all the way up the protocol stack
to connect a PC to the Internet.
