yeah, this makes a lot of sense, especially if you plan on doing some collection like (e.g. in a puppet function) without storeconfigs

We use this sort of functionality in iclassify quite a lot. It'd be nice to have here also :)

Couple of examples:
- "what vms are on a particular physical host" (get "hostname, classes" where "vhost_hostname:host10")
- 'what nodes are on each fileserver ip' (for each fileserver ip, show the hosts with that IP in facts and a particular class, count w/ wc, then total the whole thing per ip and overall)

I'd like to up-vote this feature.

Thanks
