This is exactly what I was thinking of too :-)
So when an LDS gets a web service added, it tells every peer in the VRS
network about this? Otherwise they won't find out about the new service? This
will cause more network traffic than just having a central Service Discovery
Server to which services are added, but will be more robust as maybe all the
thousands of VRS nodes know what services are available (without asking
someone else).

Didn't you say you wanted every peer to know of all the webservices? Then
central lookup servers wouldn't be necessary.
Maybe Lookup Services (or Service Discovery Server) suit better on central
servers where anyone can ask what services are available (no information
about who provides the services are exposed though). VRS is a p2p "thing"
(didn't know what to call it :), but everything might not have to be p2p?
