Steamed BAS

Most times central conditioning systems in residential buildings provide heat at times when no occupants are present. And in most rooms occupancy follows a regular schedule. Shutting off radiators, perhaps with a manual valve that does not permit air venting (between radiator and air vent) might be acceptable in some circumstances. I suppose a quarter-turn ball valve would be OK.
An automated valve that linked to room or central control might also limit steam supply to times a room is occupied and to a selected temperature. I am interested to hear of experience placing steam terminals under BAS control by shutting off the vent rather than the main valve.
Response will be of value, and will be acknowledged, in “Steam Heating: Past, Present, & Future” presentation at the ACI 10 conference, April 2010

I believe
Danfoss or Honeywell, can't remember which, make electrically-operated actuators for TRVs. These could be wired to be controlled from a BAS.
If I find the old thread where this was discussed, I'll post the link.
