Bunnie Huang of X-Box hacking fame and many other cool video/hardware engineering marvels has a new crowdfund going for a video processing box.

It seems like this would be a great platform for Hyperion and would be a great way to show commercial non-infringing uses for allowing decrypted video.
With the NeTv (and NeTv2) you could input HDMI, get the color data, output over LED signals over GPIO, and skip the painful hdmi->composite->usb-framegrabber steps.
Anyway, just though it would be interesting to put here.
