 codec? Isn't it just a relatively simple format with jpeg2000 in it?

 color science that is under heavy development by RED.

 Check out all the color filters in libavfilter, including lut3d.

 card for a huge speed benefit over CPU.

 I wonder what this has to do with the software implementation.

 > The R3D SDK is kept up to date, and supports Red Rocket.  But if
 licensing prohibits that, then I suppose the alternative would be to write
 a decoder from scratch.

 Isn't the issue just about supporting some random pixel format, just like
 with XYZ with D-Cinema? (recently added)

 > In that case, it seems unlikely that ffmpeg developers could keep up to
 date with the color science and perform the debayer and raw conversions
