I like the idea, it's a rather elegant solution. Currently the standard and ugly ways seems to be to either invent your own variation of USB connectors (with extra pins, e.g. USB +19V DC for the external DVD on the Dell Notebook I'm typing this comment on) or to push a unholy amount of juice (2A? 3A?) through those tiny (e.g. Micro-USB) connector pins. Or even bridge two USB ports. Will there be some kind of standard API to switch ports to high-voltage operation? Will we see this getting widespread use? Or have mobile devices settled on such low power consumption that all the effort isn't even worth thinking about?
