While I realise you mean USB powering the NXT, one thing that also
sprang to mind is would it be possible to get the NXT in some cases to
act as a USB host as opposed to a device. This would depend on how
much of its USB stack is implemented in hardware DSPs, or how much is
simply Firmware.
Then adding a 9v powered hub and some USB based IO makes it hugely
extensible. Again - going back round to the PC powering the NXT as a
device, it could mean for a very large bot, you could add a larger
battery and power the NXT from it.
