What would it take to get DNG hardware decode/encode acceleration?

Any experts out there want to comment about how possible it would be to create a custom PCIe card that could decode and encode DNG faster than software CPU? Wouldn't this be a way to insanely accelerate LR? Don't video editors already have mpeg hardware accelerators? Could we have photocards in addition to videocards?

It's a good idea in theory but... Video hardware accelerators went out of vogue many years ago because, by the time 3rd party developers could get a product to market, CPU and GPU development had overtaken them. I know Avid use a Blackmagic Design breakout box which they claim accelerates renders of their DNx codecs but, if that's true, they'd be protected somewhat by the fact that it's their codec.

I mean video gets CUDA core acceleration. Is there no photo decode-encode equivalent?
