One question I didn't get answered (or, if I did, I missed it!)
What IP address do I list in the bb-hosts file for the servers (the ones it can't really see, but the proxy can)?
Since I can't ping those hosts from my main BB server, but I still want those hosts listed- I'm a bit confused.. :-)

bbproxy is written so it can run as a stand-alone application. So unless you want to run network tests against the cluster nodes (your next question), then you can just copy the bbproxy executable over to the head node and run it by itself.
However, since you probably also want to do a ping test of the cluster nodes, it would make the most sense to do a Hobbit server installation on the head node. The you would disable everything in hobbitlaunch.cfg, except the bbproxy and the network test tasks.

What is the typical or preferred way of "running bbproxy" ? Do I simply fire up the bbproxy executable, feeding it the few options it needs, or do I set up a "hobbit server" on that node with specially-configured files found in ../server/etc?

Hi- can someone briefly explain how the bbproxy stuff works? We have a cluster whose "head node" is accessible, but the cluster nodes are hidden behind that server.
If someone can explain how something like this is set up, that'd be super..

Since your cluster nodes can talk to the head node, and the head node can talk to the hobbit server, the most simple solution would be to run bbproxy on the head node of the cluster.
Your cluster nodes would then use the head node's bbproxy as their BBDISPLAY server. bbproxy on the head node would be configured to forward messages to the real hobbit server.

I've used zeros:
0.0.0.0 some.host # noconnMaybe "noconn" is not necessary - I found at one time, Big Brother seemed to want to ping 0.0.0.0, so I started putting it in.

I'd put in the real IP-address, even though you cannot talk to it from your Hobbit server, and then a "noconn" so that Hobbit doesn't try to ping it from the normal server.
The reason I put in the real IP is because this shows up in various places, e.g. the "info" column. And it's nice to have at hand when you need to do something with the system.
