High level ideas

Some presumptions: (these aren't necessarily set in stone, if anybody has any other/better ideas bring them up!)

• system controller is a raspberrypi3, running raspbian.
  • or 2 raspberrypi's in an HA configuration??
• python3.
• json.
• ansible used for deployments.

These are a little more "out there". They're what I (Dan) would do if left to my own devices, but if anybody has a problem with them we can definitely do something else:

• microservice software architecture.
• ØMQ (aka 0MQ, ZeroMQ) used for messaging.
