We seem to have drifted (no pun intended) from runway occupancy to wake separation.
Well if you knew anything about the subject matter you'd realise you can't consider one without the other.
edit: For the OP Luton EGGW may be worth throwing in the mix too. They don't have a full length parallel taxiway at either end, when busy they have to be very adept at moving the traffic, and the flight crews have to be on the same page too.
