Sorry for the empty email.

Yes, you can run cfrun for a certain group of hosts.

i.e. "cfrun -v linux" would run on all linux hosts.

My understanding is that the cfrun classes are defined in the cfagent 
config. cfrun pings all hosts and tells hosts of a certain class to run. 
It says "hey everyone, I want only group x to do this."
