Great progress, Dave!
Nathaniel, will this be usable by the Magnetometer testing volunteers
that you have lined up? It seems that if remote users can acquire the
data via a websocket connection, we have enough connectivity for a
beginning array of a (few) dozen or so. How much security can we skip
over just to get some testing done?
