Another way you could do this is use a phony shell and the execl function
from the startup. Request a second password , hangup and call back the 
number associated with the password. It's a little involved but it is
absolute. A shell with an associated password file is all that would be
needed , along with a copy of cu to do dialing. If you don't know how to
go about tty handeling leave e-mail and I'll send you a few skeletons.
