If you run ppp in the background (with -auto or -ddial) with DISPLAY
set, ssh will pop up a dialogue (ssh-add style) on your display.

If you need to do it at the chat stage (for login/password w/ securID
cards), you can specify your chap password as ``!program'' or specify
your chat script password as ``!program''. If ``program'' is x-aware
it can look quite pretty. See the tcl examples in
/usr/share/examples/ppp.
