Hi, Joel: It depends on the distribution of service provider. It may need some experiental data to see how much percentage of the service provider is enough for a relative efficient service discovery method.
SEP proposal tries to check the routing states in the peer to find the service provider. One method to improve the search success rate is to send a LookupServicePeer message out and make the message traverse the overlay hop-by-hop until matched entry is found. It also set the max-hops for the message to avoid the message goes forever. Regards!
