How about this situation:
The ports are dial-up, and mostly inbound wats lines, the users are
calling in to pick up frequently updated files.  There are >1000
login id's and about 8 inbound lines.
My solution was to use a login shell that just accepts their requests
and hands out the files unless they ask for a menu of other choices.
A separate process is forked off which periodically stat's the tty
line checking for a maximum idle time and total on-line time mentioned
in the comment field of their passwd file entry.  They mostly don't have
permission to write files or a home directory, either.  If either time
expires, the other process forces the line to drop.
