The current GC liveliness entrypoint is in LiftServlet.handleAjax() which
calls liftSession.updateFuncByOwner().

There's no extension point for what you want at the moment although it would
be fairly easy to add something to LiftSession.

The closest thing right now is LiftSession.onBeginServicing where you can
add you own function and correlate the request session id with the objects
in your own application.

Hope this helps,
alex
