Hi all, I'm new to twisted but am having trouble getting my head around how to structure my application with this new approach. I'm creating a server that accepts client connections and then drives the client according to a simple, line-oriented protocol. The server sends the request (1 line), and receives a single lined result. I'd like the server to offer an API to generate the correct request lines to the client, and return the results (either blocking or asynchronously). So in effect, I have two event loops, one from the Network and one from whatever's sending the API requests (command line?). Can anyone offer any guidance on how to tie these two parts together? My instinct is to have the two event loops in separate threads and communicate through Queue.Queue, but that doesn't seem to follow the spirit of twisted. And I guess I'd have to somehow tell the reactor to poll the Queue object for requests, and then dispatch it to the relevant method to send out to the client. I've looked at threadedselectreactor but can't seem to find any decent documentation to even decide if it's write for what I want. Any advice would be much appreciated. Thanks, Paul
