I think of that kind of chip as a good gateway running linux.  I hadn't thought they
or Atmel's AVR32 or SAM926 chips were low enough power for a sensornetwork node
since they talk of clock speeds like 100MHz, but some may run slower OK -- they do have some
sleep modes.

I'm also thinking of using SAM926 as a sensorboard for a ecosens1 mote because it
has a digital camera interface, but I would just use it as a peripheral to tinyos-2.0.
Linux will take more memory, but...that can also be used to hold and reformat
and compress image data without any porting code effort.
