What about the method which is linked two clicks away:

	http://www.rhythm.com/~ivan/pdfs/sketch2007.pdf

Basically they store a motion vector for each pixel, and blur the image afterwards. Easy to implement, better than simple image space blurs, but of course still with drawbacks: only the object which is frontmost in the concerned pixel gets blurred correctly. Occlusions and transparencies cannot be handled perfectly well.

Cheers,
