[Twisted-Python] Perspective Broker vs AMP

You may have seen my recent posts about data comms across nodes of 
server network.

Phil kindly pointed me towards PB and AMP which, after some fiddling 
both look viable. However, I do have one question: If clients can 
request remote data from the server, is the reverse possible?

As I understand PB, a client can get the root object of a 
PBServerFactory, thru which it can call methods with the 'remote_' 
prefix. I'm not clear how this can work in the other direction. As for 
AMP, this seems similar - the client uses callRemote() to execute remote 
methods on the amp server.

Since I have node clients all talking through a server, I need the 
client to make requests to the server, which in turn requests the 
appropriate data from the corresponding client.

Thanks for any advice on this
