> 4) How much do the DAC, reference, op-amps, resistors, capacitors, drift with time? 

Assuming constant temperature and supply voltage...

What is the time scale for parts drifting?  Is it very low frequency so well 
within the loop bandwidth or is it jumps that will be hard to filter out?

What happens if temperature or voltage is not constant?  Are the changes 
reasonably linear with temperature/voltage?

These are my opinions.  I hate spam.
