First, make sure you can get the part of Analog if you are making more than one.
They are really hard to get right now (I have several on order since May and
they're telling me April 2001) and will cost a lot more than they quoted
earlier.

I have used this exact setup.  Works great!

You can keep the one input always set to the ADXL device and integrate the
results constantly (hint hint).

The PWM output you can switch back and forth between two servos using a logic
chip (demux).  Then you can update them as frequently as you want.  I had a
design using a GAL to use the two channels as inputs, then flip one pin and some
software to turn them into outputs, and they would go out on another two pins
from the GAL.  Super-accurate mixing, only used 3 pins to get 2 inputs and 2
outputs with .5uS resolution.  The logic was all very fast and short code,
leaving lots of codespace to do things like variable mix ratios, expo, etc.
