Sessions and servers

Any kind of binding creates a session. As mentioned in Section  binding to a service creates a service session or service connection. Binding to a facet also creates a session, but of course we do not call it a service session--service sessions are only created with warrants.

Because netlets and services are different--netlets fulfill services--we often refer to netlets which deliver services as servers. For example, there may be many netlets which offer access to one service; they are alternative servers to the same service. The distinction between server and service is a fine one, but it is accurate and helpful.
