+networks using zeromq.  It has these key characteristics:
+
+@itemize
+@item Zyre needs no administration or configuration.
+@item Peers may join and leave the network at any time.
+@item Peers talk to each other without any central brokers or servers.
+@item Peers can talk directly to each other.
+@item Peers can join groups, and then talk to groups.
+@item Zyre is reliable, and loses no messages even when the network is heavily loaded.
+@item Zyre is fast and has low latency, requiring no consensus protocols.
+@item Zyre is designed for WiFi networks, yet also works well on Ethernet networks.
