Major Description
BYON is all well and good if you've already got your list of nodes in a YAML file somewhere, but a pain in the butt if you want to use something else to do your provisioning (or integrate with some other way of getting your nodes, from a service/db/whatever), since to use it programmatically, you need to serialize your nodes to YAML and then load them. This...is annoying.
There's a CacheNodeStoreModule (to go with the default YamlNodeStoreModule) in jclouds for BYON - it'd be really handy to be able to take advantage of that.
