Well, ethernet (PoE) is going that way, but in a
bigger sense (ca.
44V at 350 ma.).
Thinking about it, most of my machines have power available on the
ethernet conenctor. That's the AUI connector, of course :-)
Most modern PCs will continue to supply power to the USB connectors
even when "off" (soft "off"), so mobile devices can be charged even
when the system isn't being used.
I am sure there are more efficient ways to do this.
And USB as a cheap source of power makes all of those really cool
devices--shavers, foot warmers, fans, etc. possible.
Do does a bench supply...
Anyway, I dnon't particularly want to sahve near my computer. Shaving
produces a lot of dust (consisting of small particles of hair, of
ocurse), which I'd rahter didn't end up in my systems.
And with only 2.5W availalbe (after negotiation, 5V at 500mA), I don't
think any of the heaters are going to do a lot.
