I would concentrate on feComponentTransfer and feColorMatrix for the palette reduction:
See http://www.w3.org/Graphics/SVG/IG/resources/svgprimer.html#feComponentTransf er - there are some examples of "posterizing" there I think. Also, the animated example at http://srufaculty.sru.edu/david.dailey/svg/matrixFilter.svg may provide some notion of how to combine these filters into chained effects (either Opera, FF6 or IE/ASV should allow you to see it - I was very pleasantly surprised to see FF now handling this!). For the dithering part, yes, I would look at feConvolveMatrix - and there are some examples of using it in the example above. Webkit and IE are a bit behind the others in filter implementations.

In raster this is generally done by reducing the colour range to about 256, then using ordered dithering. The result is something like this: http://bisqwit.iki.fi/jutut/kuvat/ordered_dither/scenebayer.png Could the feConvolveMatrix filter do this? (I can't test it just now because it appears to be broken in Chrome.) Thanks, Colin.
