Hi Dave,

Interesting, not as much change needed as I would have guessed.

Now I'm dying of curiosity... what is your impression of the usefulness 
of RFC7090?  It always struck me as a lab curiosity: in fairly 
artificial cases where a bunch of CPU boards are powered up 
* a room full of machines with a master breaker
* a rack of CPUs
it would be a big win, but that is a fairly unusual setup in the areas I 
hang out in.

On the other hand, we have a customer that currently has up to 4 units 
in a rack, and in the future possibly more units in a rack, that could 
possibly benefit from RFC2090.

Best regards,
