David, a couple of questions.

I see that in your fencing tests you just stop systemd unit.
Shouldn't pacemaker_remoted somehow notify crmd that it is being 
shutdown? And shouldn't crmd stop all resources on that remote node 
before granting that shutdown?

Also, from what I see now it would be natural to hide current 
implementation of remote node configuration under <node/> syntax. Now 
remote nodes do have almost all features of normal nodes, including node 
attributes. What do you think about it?

Best,
Vladislav
