Back in the old days diesel fuel was sold to farmers, bulk delivered to a
home tank, for tractor use only, cheaper and exempt from road use tax.  It
was color dyed for obvious reasons.  Occasionally a pickup truck would be
seen in  town with a splash of reddish purple around the gas cap.

 I agree, the electrical meter sample with medical plug sounds reasonable,
but I unfortunatly I found it after posting my statement.

No, but that's not a good analogy. The solar panels are more like offloading
work to an Intel or AIX box than running it on a processor that you were
sold at a reduced price under certain T&Cs.

I like the "medical power socket" analogy very much!

The courts will (presumably) look at the result, which is pretty simple:
non-eligible work is running on a box that was explicitly sold *at a reduced
price* with Ts&Cs defining "eligible work". The zPRIME users are plugging
their TVs (or more likely their space heaters) into the medical socket.
