ok, so to redirect this thread...  aside from implementing a solution similar
to what we used a few years back with as5300 series which was to;
	sh user (caller in as5300)
	parse the output for the user we want to get the Vi#
	sh int virtual-a # stats
	...or clear int virtual-a #
	...depending on what we are wanting to do.

aside from resurrecting that code and altering it for the 3640, is there a way
to get the current input/output from the 3640 without knowing what vi port
that the user is logged in as.  I don't even require the ability to drop the
user, but do need to be able to intelligently poll the 3640 for any active
sessions to determine bandwidth usage.  (any sessions that have ended have
already transmitted their stop packets so we are not concerned about them).
