Okay, so the requirements, distilled:
1) sun
2) moon
3) stars above

:)

Here's a bit more legwork you might be able to do: Can you put together 
in one place some samples of every single colorspace format you would 
like to support? Also, run them through the existing lossless coders 
(like HuffYUV) and post some numbers so that a potential developer knows 
what numbers to beat.
