Ross,

I am considering writing a custom tool that converts them to RGB palette on the fly, and back again. Since the colormap is so simple, I can hardcode it into the tool and not worry about losing any color information in either direction.

Using an RGB palette for this makes perfect sense in my opinion.

Also, even full CMYK data should likely compress very well with if you combine it with say flate (aka zip) compression, seeing you use only three colors, as Chris noted already. Just don't make your strips/tiles too small, I guess. If it's dithered data, it may be best in this case to *not* use prediction, possibly, though you'll have to test to make sure.
