I'm new to twisted too and work on a similar project now (twisted
on serverside and flash and C# on clientside).

I'm not sure if it's the right way in twisted, but this example
receivs lines from one connection and writes them to all other
connections.

from twisted.internet.protocol import Factory
from twisted.protocols.basic import LineReceiver
from twisted.internet import reactor

class Chat(LineReceiver):
    def connectionMade(self):
        self.factory.addClient(self)

    def lineReceived(self,line):
        self.factory.sendAll(line)

    def connectionLost(self, reason):
        self.factory.removeClient(self)

class MyFactory(Factory):

    protocol = Chat

    def startFactory(self):
        self.clients = []

    def addClient(self,cli):
        self.clients.append(cli)

    def removeClient(self,cli):
        self.clients.remove(cli)

    def sendAll(self,msg):
        [cli.sendLine(msg) for cli in self.clients]

def main():
    f = MyFactory()
    reactor.listenTCP(8000, f)
    reactor.run()

if __name__ == '__main__':
    main()
