My guess is that someone will come up with an inexpensive, reliable way to put a heat collector, which will basically look like a car radiator the size of a rear rack door, directly behind the hot air coming from the systems in the rack.

You tuned in late, unless you're focusing on "inexpensive". See the recent thread on "cooling door". The problem with a heat collector on the back of the rack is that having collected the heat, you need to put it someplace else - in the case of the IBM unit, it's moved elsewhere via chilled water.
