group membership and terminal lines

[Andrew Morgan <morgan physics ucla edu>]

Another module that someone might like to think about it one for
granting permissions to a user that logs in at the console. (This was
first suggested a while back.)

Currently (pre PAM), all the group permissions are granted based on
the /etc/group file. For example, Slackware has a "floppy" group that
users can be members of and get access to a box's floppy drive. It is
clumsy (or worse) to grant permission to use the floppy drive to a
user when they are telnetting into a Linux box from the other side of
the world...

A better PAM approach would be to have a module that can give extra
group permissions to a user when they login from a specified terminal
line. This need not be limited to the console.

Does anyone have any thoughts on implementing this?
