The question isn't really how to do TCP on a phone line to allow a
micro in, but rather how to build something like a circuit-switched IP
network. As evidenced by the mail on the list, lots of people have had
user-initiated dialup IP for some time. Most implementations just run
IP over the wire (with something like SLIP or compressed SLIP as the
data link layer), with acceptable performance. The remote procedure
interface is interesting, but you need to build some sort of reliably
data link layer under it ... I wonder if it really buys you anything in performance?
