Time restricted access

Hi all,

Can anyone think of a way of restricting access on a time basis either to desktop pools or using some sort of from condition? So for example Pool A is only available between the hours or 1800-2300 or Pool A (or all pools) are only available between the same hours remotely.

I can't see a way of doing it myself other than to tag them to one Connection Server and schedule stop and start the services which is pretty lame.

Cheers!
