[Twisted-Python] server push data to client

[vitaly at synapticvision.com]

hi,
what could be the way(Producer/Consumer?) and simple,basic example to  
push data(~10Kb) from Twisted based server(that listening for incoming  
requests) into  client side(for example FLEX) not as a response to the  
incoming request, but occasionally, triggered by server side???

In traditional client/server arch, the server is listening, accepting  
and responding to the client's requests, but here I'm looking for  
something that initiated from server itself and pushing data to client.

Appreciate the help.
