Doesn't this mean that the ground might get contaminated by power supply 
noise? From what I've understood, a cap is only needed between the rails 
for stability.

Has anyone experimented with sense/force ground?
Idea being that sense ground has minimal current through it and is only 
used for references and no loads.
