when i was at unsw in the late 70's there was a lot of work being done 
on associative memory as a different way to organise disks. the 
microcode in the drive was programmed. i didn't hear much about it after 
i left, but as far as i know it did work and quite well.

i think the real problem, and the same problem beset efforts at 
non-turing cpu architectures (also tried extensively at the time) and 
probably caused the ultimate demise of things like pick etc is that the 
world became a place where general purpose computing was needed more 
than any other sort. why dedicate parts of the hardware to one software 
paradigm when a good general purpose os like unix could make it possible 
for many paradigms to exist on the one machine?

non-turing architecures went the way of non-binary switches - people 
just can't think well enough that way, so we go back to the comfort zone.

xml must derive some of it's success from the fact that it can sit on 
top of many architectures and therefore coexist with many things (like 
databases).  i'd suggest the way forward is more of the same, not an 
architecural shift.
