Nobody is mentioning the most interesting use for a voltage
controllable delay with very short delay times - analog physical
modelling. To do 'tuned resonator' types of blown pipe emulations one
needs precise voltage control with sub millisecond resolution, along
with voltage control of feedback. If it has to be digital to achieve
that much control, so be it - but it will take a purpose-built
design, not a hacked up pedal.
Check out this article about Ron Berry and his analog acoustic
modelling techniques, if you are not already familiar with him:
http://www.sospubs.co.uk/sos/1997_articles/jul97/ronberry.htmlI've often wished to talk with him in greater depth - I'd dearly love
to explore this side of synthesis. I wonder what technology he used
to build his own delays...

Feedback on the suggestion, yes! On the delay, maybe not. That's
what the Time Machine is for! A 'little' delay would free up a TM to
do 'bigger' stuff.
Remember, I suggested very small delay times: 0 to 5 ms, or even 2.5
ms. Do you still need oodles of bucket-brigade for such short
delays? If not, then the chip problem is moot, no?
