Greetings, I have a "daemon" that is written in python (with some C extensions). The characterstics are: . A infinite loop, and in each cycle of the loop there is some processing going on. . During the processing, (everything else is blocked) so that she can do things uninterrupted. This is already a functional application. Coming to my question, currently I would like to provide it with a administrative interface that can be controlled over the network. In short, I would like it to be also: a) network daemon b) a very simple challenge/response type protocol to control the behaviour of the daemon. Obviously, "twisted" on the surface looked to be a very good candidate to get this up quickly. Since, I would be using a "reactor" interface, do I have to create my own "reactor" by subclassing say the TCP interface. Or, is there a easy way to integrate the reactor loop (.run()) with my loop?
