Walt, I disagree.  Even with one RAW file different RAW developers 
produce different results.  What we want to compare is final output.  
Canon RAW files are different form Nikon RAW files are different from 
DNG files.  We want to optimize the entire imaging chain and clearly 
what's optimium for one person's technique might not be optimum for 
another's.  What you're suggesting is like handing film from a 
single-use camera to a pro lab vs. taking 100UC from a Leica to the 
corner one-hour lab.  Neither is likely to be optimized.
