Peer-to-peer RelayServer #7
Description
Rather than going to a central UpgradeServer, we should have one in every UPGRADE protocol. This allows us to get rid of 1 moving part, namely the separate UpgradeServer process required in the current solution.
The UpgradeServer instance needs to discover other UpgradeServer instances in other members dynamically. Perhaps this can be done by getting all members, their physical addresses and ports, and scanning the next N ports?
The UpgradeServers talk to each other when sending a message to one/all members.
