Ooh. Please share. You're the first case I've seen in a *long* time where
getting the BTU's *out* of the rack wasn't more of a challenge than getting
the watts *into* the rack. Once you're talking about "datacenter" sized
spaces, those BTU's add up, and there's plenty of current spaces where the
limit isn't the power feed into the building, it's the room on the roof for
the chillers....
