That's correct.

The fact is that a service oplet such as Hello runs on the Accelar just
like a daemon program and provides its service to the client such as
HelloClient upon request.

You can interface a service oplet within the same ORE. For remote access
you communicate a service oplet from a system inside the network through
Java socket or RMI.

The ORE ANTS is a good example that meets your requirement. Actually it
makes the communication in the same way a Java program does.

Sure. And, you need to learn about these 8600 features although the
1100B provides QoS support by a handful of forwarding priorities.
