 * RemotePeer objects represent TCF agents that Locator service discovered on local network.
 * This includes both local host agents and remote host agents.
 * Note that "remote peer" means any peer accessible over network,
 * it does not imply the agent is running on a "remote host".
 * If an agent binds multiple network interfaces or multiple ports, it can be represented by
 * multiple RemotePeer objects - one per each network address/port combination.
 * RemotePeer objects life cycle is managed by Locator service.
