with zeroconf, peers broadcast queries and respond to queries that they see broadcasted. this is a more standard way of doing local peer discovery.
sbot local peer discovery is basically just hello packets repeatedly broadcasted (every 10 seconds) - there is no query/response.
UPnP is used to tell the router on your network to forward a port to you from the WAN. eventually we might want to use this to let home nodes automatically become pubs.
