Yep. Specs stated or implied in your first post were: rack-mount outlet
strip, per-outlet power measurement, UL approved, price to beat is
$161/port. In the absence of other data, I figured kludginess vs.
~$80/port savings was a good trade-off.

The APC 350 VA "fat power strip" UPSes can be had for $30 each.
$95/port vs. space.

But they don't want to pay very much for the data.

And, AFAIK, this is normally reflected in the pricing of the rack space
- when you pay for a 15A or 20A circuit, you're paying for the electricity
to bring the heat in and the cooling to take it back out.
Again, it would be really interesting to see the business case for this.
