of course you can run those in a datacenter and connect remotely to them. ssh and web+https start on boot. forum users suggest that 40 usb asic miners (block eruptors) can run on a single raspberry.

I did not understand why to include a second R pi, thus did not answer earlier, did not make sense. there is no way how the second one would take over the mining coordination in case of the failure of the first one.
