I haven't followed earlier discussions, what's bad about that (in a nutshell)?

That "power" doesn't exist on all platforms, and even on UNIX: does that "power" go that far that it works without memcopy? E.g. - a filter needs to paint just a few pixels on a video frame - doesn't the full uncompressed frame need to be piped forth and back?
Also, filters often do and require more than just a range of data to do their work.
