Net services is a network based implementation of the service/subscriber architecture found in in Eiffel utils. It implements a service registry and a service provider, connected over a TCP/IP link.
The protocol works like a subscription server. There is a single server that can support multiple clients. The server provides services, each one identified by an unique string id.
Clients can connect to the server, and subscribe to services, which represent objects on the server. When a client subscribes, it receives a serialized version of the service (object); and each time the server-side object is updated, it sends to it(s) clients serialized info about what changed in it.
A client can unsubscribe at any time.
