Out of price range in singl= e units, but I don't know where the price breaks kick in. =C2=A0Dual-co= re 800MHz ARM should be plenty of power for the GigE ports.

I think to get any sort of platform like this by a majo= r vendor, we're looking at needing 10K quantities, which I just don'= ;t see happening, without a really well-done kickstarter type campaign.

OTOH, a kickstarter might be a good way to get a largis= h group-buy together for some of these more dev-minded platforms.

Intel Avoton/Rangeley looks great but very expensive; boards are around $30= 0 without radios, case or PSU.
