in general you do [whatever you want] in response to some event, which might be connectionMade, 
dataReceived, a periodic call from LoopingCall, a one-shot event from reactor.callLater or any other 
API that informs you about certain events. You can take your code, as in your example, and run it 
inside one of these callables or another callable you trigger from there. You absolutely do not have 
to set up everything before you call reactor.run. Just create a callable (at any time), make sure 
that whatever should trigger it gets a reference to it, and then call it whenever appropriate. Also, 
look at Deferreds, they provide an API for callbacks, chaining them together and other useful stuff.
