Controlling peer activity in a peer group
Hi, I'm sure the answer is staring me in the face, but I just can't see it.
I can control which peers join a peer group but how do I control what a peer can do once it is in the peer group.
There are two scenarios I'm trying to figure out:
1) I create a peer group and my peer joins that group, my peer publishes a service into the group. I want other peers to join the group and load an application to use the service. But I do not want those peers to publish their own services in the peer group.
The only way I can think of doing this at the moment is to write a custom discovery service that prevents all guest peers from publishing advertisements into the peer group.
2) I create a peergroup with a peergroup service defined, I get one or more peers to join the group to provide redundancy. Again I want other peers to join the peer group to use the service but I don't want them implement the service or start publishing their own peer services into the peer group.
I realise that these scenarios are not pure P2P as the peers do not have equal status, they are more like a classic server/client model. This must be a fairly common scenario, or am I just not thinking with a P2P mind set?
Any thoughts or comments appreciated.
