But its got USB. And USB is powered, right? Is there any reason not to use
that source?

Powered USB port can deliver up to
5V and 500mA, so that is
insufficent for LEGO motors.

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.
