Pycon 2014 talk proposal. I'm open to any and all feedback. Would you be interested in this talk? Are you more interested in the generalizations, or the specifics? What do you think would make this talk more interesting to an even broader pycon audience?

I'm working on something that takes physical hardware and allows one to add additional behaviors to it. In the end, I'd like the API to present the modeled logical item as a single entity in code with all state flattened. If the logical objects that add behaviors to the physical devices were 1:1 with the physical devices, then it would make sens…
class PhysicalDevice(object):
def __init__(self, channel=0):
self.channel = channel
self.physical_state = False
class LogicalDeviceBase(object):
def __init__(self):
self.logical_state = False
