As well as rather a lot of reading code and RFCs I started into coding today. First task was to replace the asyncore communications loop with a Twisted Protocol object. Once I got straight which pieces actually relate to the system, and which are part of the asyncore loop it worked fairly well. Gave up on trying to mimic the synchronous operations, they are reliant on rather low-level checks to see if the ports are still open.

Anyway, still another 2 hours of work to get done today (still doing the 9hr/day thing), but I need a break just now.
