	I'm working on the distributed scheduler (https://blueprints.launchpad.net/nova/+spec/distributed-scheduler), which is the first step in adding the sort of host selection across a complex installation. Sandy Walsh has added the ability for individual hosts to report their capabilities up through the zone hierarchy, where they can be aggregated for more efficient request routing. This will provide the basis for a much more robust means of specifying a host than just "availability zone", which will probably become just one of many potential attributes that one can select for.
