Wow, this looks really nice.  

In the windows world "DScaler" (http://deinterlace.sourceforge.net) is widely acknowleged to be one of the best quality viewers (visual quality that is, program itself is horrible).

You might take a look there for inspiration.  They have a couple of clever algorithms to detect which sort of de-interlace works best for different situations (video, live tv, etc).  Also, the denoise filters would be a fantastic "nice-to-have", and would probably really boost compression ratios as well
