You were going to use the KnC's hosting for the Jupiters, weren't you?
AFAIK, the points 2, 3, 4 and 5 are covered by a hosting fee of $350 monthly per device.
Aren't they covered?
Do you list them just in case?
Or do you want to host the machines elsewhere?
good question! I can't see why we shouldn't rely on KNC hosting, since:
1) new machines could provide hw / sw errors, that could be resolved with more ease by KNC staff.
2) I can't see how we could make everyone agree on a different single hosting location
3) lack of trust (aka foresight)
