Chuck Moore is definitely one of the great computing heroes, especially if you're an idealist.

The problems with the GreenArrays product seem to be that it's too separated from the rest of the world, and in order to successfully interface peripherals (even SRAM, as covered in this video) to it requires completely grokking this alternate way of doing things, in addition to understanding the low level details of absolutely every interface.

Maybe I'm in the wrong circles, but right now if you can't shoot UDP packets out of something it doesn't really meet the minimum baseline for connectivity. If you're going to head off on your own (and certainly for energy purposes there would be good reason to do so) you need to have a simple bridge back to more standard land.
