Things Bus
We want to make a super-easy-to-integrate-with way to handle sensors and actuators around the space.
Alpha Quality: thingsbus python + zeromq system
For details of this system, see https://github.com/eastein/thingsbus - more documentation to be filled in here later.

Issuing commands
Commands for items should be sent to a queue, the controller/interface for the time should be subscribed to the queue and process the commands, queues should be laid out in a similar way to topics. Messages should also be json and well formed and documented.
