This would be a large amount of progamming also in the chap protocol there
is the concept of periodic rechecking of the peers password(sent as a hash
across the line) while the connection is running
ie  need to re-program the getty to do lcp(quite hard ~10 weeks)
 & introduce into slirp an lcp layer (even harder ~ 6 months)
_OR_ setup pppd (about 1/2 hour)

No not quite - chap can use the system login databases(shadow,
nis,/etc/passwd whatever) or alternatively if you dont want to give your
ppp users login priveleges the passwords can be stored encrypted in a
special file read only by root
