Implement support for stateless-server protocols in comm.js

[marc-portier]

Expanding on the idea of request-response protocols it would be great to allow building actual service providers that can answer to multiple independent clients.

This is about chat-room type stuff, right?

(i.e. what's the relation to #15?)

Euh yeah could be done similarly - when creating this I was more thinking about other use cases.

I.e. More thinking down the lines of "I've written a custom block to generate e.g. a random letter" and I have an easy way to offer that "service" on the scratchnet. It is a bit like request-response type protocols, but without a "connect" phase over on the service-provider end: he just answers to the one making the request.

We'll have to think about identifying the request and sending the message back to the correct client without prior 'connect' relation between them.
