I'm surprised there's a demand for this degree of power subdivision. Other than regulatory issues[1], it wouldn't be terribly expensive or difficult to modify an existing low-end PDU with multiple small-amperage breakers. It may even be possible to get reasonably priced[2] self-resetting ones. The main trick would be getting oddball values like 3.75A, though four 3A ones would allow the sub-tenants to run at full breakered capacity, while maintaining 80% overall. Perhaps there's a hardware startup in this. How much would you pay for a power strip with individually breakered outlets? [1] Could be as practical as Perfectly Spherical Cows, I realize. [2] Under $20 even in small quantities

oh man, I spent a fair amount of time talking and researching this before hand... and yeah, it's probably possible, but you need a guy with significantly more knowledge and experience with power than I have to do it. Oh, and, my understanding is that it probably wouldn't be as good as my hacked up perl script, either. Apparently, there is a lot of wiggle room in the power level at which breakers trip. As for your "How much would you pay" question, probably not a lot. for the first cabinet I'm spending under $100 each for used metering PDUs (and giving every user their own.) After the first rack, I don't know what I'm going to do (that /is/ a reasonable used price, if you look around, but I would need to pay about twice that for a guaranteed supply)
