Stupid and yet simple:

/usr/local/bin/ppplogin (login shell):

#! /bin/sh -

stty crtscts
tty=`tty`
tty=`basename ${tty}`
exec /usr/sbin/ppp -direct "${tty}"

/etc/ppp/ppp.conf:

ttyd8:
 set debug lcp
 set ifaddr 206.55.67.17 206.55.67.72
 set timeout 43200
ttyd9:
 set debug lcp
 set ifaddr 206.55.67.17 206.55.67.73
 set timeout 43200
ttyda:
 set debug lcp
 set ifaddr 206.55.67.17 206.55.67.74
 set timeout 43200

.... la de da, etc.

Not true dynamic PPP in that you are reserving an IP for each serial port.
However, this does prevent you from doing foolish things like overcommitting
and it does make administration simpler because you can always reconstruct
who was on a port given a hostname or whatever with very little effort.
