        of the session. After that, it is all IP until carrier drops.
        Is there a well defined, documented protocol for this initial

Not as far as I know; but I had something like this in mind when I
rewired Rick Adams's version of SLIP for 4.3BSD. That is why slattach
waits `forever' in a sigpause(): to find out about carrier loss. If
you are a client of some dialup IP server, you might want to redial

(Those of you with 4.3BSD source can look at /usr/src/etc/slattach.c to
see how the attach works. It should be easy enough to write dialup and
protocol code that would run first.)

        How would you deal with dynamic name/address mapping?

I will leave this one for others.
