ZeroMQ does not directly support this, you would build it as an
application on top, defining your own protocol to connect clients and
I'm designing something that looks a bit like this, with peer-to-peer
message flow, and rough-grained security based on "streams" of data
rather than a topic tree. It needs to work over multicast, meaning
that you can't apply access controls at the server side.
