Thanks for your reply.

My goal is this:
1) do specific tasks
2) run the server and wait for a connection
3) when a connection is made, do tasks as instructed by the client in the 
AqapProtocol code.
4) when connection is lost, close server and go back to 1)

Shutting down the server is not necessary if I could get past the 
reactor.run(). A previous post suggested I use deferreds. So, that is 
probably what I need to. I just need to learn how to use them.

Thanks,
Tom
