In our lab we have different hardware connected (including non-x86,
mostly due to maintenance and testing drivers) and it allows us to run
more or less fresh kernels on it. Setup is pretty simple: server with
connected USB 2 serial, network, etc, power cutters, relays to emulate
power button presses for the hardware that can't be turned off and on
by cutting the main power (usual case for tablets / phones) and so on.

Now to the point, perhaps organizations like LF can set up something
like this with one technician to support this and pay electricity /
internet bills?
