Thanks very much Arne - you have picked up exactly what I was getting at.

This is the whole point. If we have a generic Peer to Peer system then the
work to be done on the server is minimal and one-off. [The example of chess
was simply to something that most people can relate to, but the more
exciting areas are domain-specific collaborative working.]

This is my main point - I'm not experienced enough to know what the best
approach is. I am only looking for simple ones for proof of concept. I
expect http would do fine for a simple demo. What would be required?

[Personally I'd prefer to use Java applications simply because I haven't
yet got JUMBO2/Swing running in a browser in less than exponential time.] I
imagine they could be browser helper applications?
