Ideally, it would be nice if we had better insight on the actual health of the backends than a simple "do they respond to OPTIONS * and how long does it take", but that's pretty much all we can do unless go full-on multicasting of info ala mod_backhand... At least the balancer is setup to allow for load balancing based on that, if the submodule/provider actually existed :)
Is there anything stopping us going the multicasting route, say by adding a hook or hooks of some kind to proxy that keeps track of known server states?
A dedicated module could then have it's job as handling the multicasting and letting the rest of the server know if a server is on or off the air, in realtime.
The proxy can then just say "which of these servers should I connect to?", and the hook will return the suggested ones in the given order.
As a dedicated module, people who don't need it can turn it off or not build it.
