If you look at the scorbit implementation, there's been a pretty massive engineering effort to make it work. Not sure the market is big enough to justify a 100$ price point - maybe I'm wrong.i guess they could. and i guess there will be a scorebit rival or two soon. A £99 price point rival would sell loads i think.
I do think Stern will release a wifi node board. Their CPU already runs linux so it should be easy to tack on.
