[zeromq-dev] ZMQ UDP "I'm here" broadcast

I am getting ready to implement a distributed messaging system to
discover devices on a network.

Our current device distribution approach responds to SSH commands with
command line (literally C/C++ iostream cout), but this doesn't scale
so well for higher volumes or longer run times. So, would like to
implement a messaging system on a couple of levels.

There will be proxy hosts that need to discover these devices on a
network. Other than predetermined knowledge of IP addresses, I'd like
for the devices to announce they are on the network with a UDP
broadcast that the proxy host(s) can respond to, on different port(s)

After discovery, proxy would connect in the more "conventional" TCP
PUB/SUB manner in cooperation with the SSH session: SSH to kick off
the service, and TCP PUB/SUB to sink messages.

Is something like this possible with ZMQ? Getting ready to get after
that "with anger" (passionately).
