There is Class E down to 700' AGL when Rocky tower is closed (i.e. a non-towered airport).....

The current TAAATS system, for non-surveillance aircraft does a similar thing. The controller enters in the ETA of the waypoint on the electronic flight strip bay and the flight progress tag moves along at a rate which would make sense for that estimate. I think it is a great idea for increasing situational awareness in non-surveillance areas (and from what I have seen on my visits to the control centres, is quite accurate (comparing it to Flightradar24 for example, where a household ADS-B reciever is picking the plane up when Airservices receivers are not).
I believe there is also a similar system for estimating positions based on ADS-C uplinks from the aircraft, but one of the real controllers on here could probably confirm that.
