I do not have any ideas on how to make that work.  However, I am wondering if there
could be a script set to run on login and logout that would report to a central
location.  The script could record the action as being either login or logout, the
username, and the date/time.  This central record or file could then be parsed by any
number of applications or scripts to report your information.  I don't exactly know how
to do this, but I would think it to be very trivial for a script junky.

Hope that helps,
