How to write a Twisted client plugin

Should you perhaps be using the tac files to run it from command line?

http://twistedmatrix.com/documents/12.2.0/core/howto/application.html#auto5

Then using your MyChat class should be easier in another program...

You have to return a main service object from your MyServiceMaker().makeService method. Try adding from twisted.internet import service then in makeService add this at the beginning: top_service = service.Multiservice()Create the TCPServer service: tcp_service = TCPServer(...)Add it to the top service: tcp_service.setServiceParent(top_service)Then return the top service: return top_service

You may also need to take a look at this excellent series of tutorials from Dave Peticolas (article n°16 is the one which is useful for your problem)

Just follow this links for docs and help:
