actually, combining what i said with what you said got me to a new idea: if the different areas on the chip were sharing inputs and possibly outputs, even with the same bandwidth tech, it would be much higher bandwidth as a group. So, for example, have a whole tape-out project devoted to something like a modular music-sampler/synthesizer. So, there's D/A A/D of a few audio/midi streams coming in, which every area of the chip gets as a feed, but also areas can talk to their neighbors directly without multiplexing, and then mixers, filters and group output. Maybe some way to "roll your own multiplexer" so somebody could use the whole chip for a variety of guitar pedals, somebody else a vocal processor, etc.
