I had a quick look at the getty sources and it looks like you could easily
put in some code to detect PPP and launch pppd with (chap|pap) instead of
login.  I saw code like this done in mgetty in the archives of the
screaming hordes.

Has anyone done this yet?  If not I'll write the short bit of code and
post the context diffs.

Basically, you can place a simple ppp detect state machine in the loop in
getname()  between the read and the login name buffer building code. 
getname()'s return value would have to be changed from (true|false) to
(unix login|ppp|nothing). 

Then do the following in getty's main loop:

getname()
if login exec login
else if ppp exec pppd requireauth
otherwise nothing

This makes Win95 PPP login real easy.
