I should probably port this option over from the OpenSolaris variant of
pppd:

     maxconnect n

         Terminate the connection after it has been available for
         network  traffic for n seconds (that is, n seconds after
         the first  network  control  protocol  starts).  An  LCP
         Time-Remaining  message  is  sent  when  the  first  NCP
         starts, and again when 5, 2, and 0.5 minutes are remain-
         ing.

Without that option, one way of doing what you ask is to use the
"linkname" parameter to force a reliable PID file name, and then just
sleep and kill the process based on the contents of that file.
