You could use zero-configuration networking for the discovery:

Then use JEP-0030 for detailed service information.

Or you could write a server-side component that has more information
about entities on your network (something like a Jabber User Directory
but for network services). Will your network entities have stable
addresses or JabberIDs, or do you require dynamic discovery?
