Completely agreed. But luckily, we're primarily concerned with the PAM
API bit! I'm sure that if we can sort that out in some general fashion,
it will be more clear how to modify login to do the right thing, or some
approximation of the right thing so its clear how we need to modify
login, Linux, etc.. to do it all right.

Agreed. Let's leave this part as an open issue.
