Yes, but then all I'm doing is presenting numbers that don't change to an 
interface, simply on the basis that the numbers represent sensor values.

If I'm running a sensor application, I'm doing it to get real-time 
monitoring of the sensors in my system.  The DCM on our boards is not 
capable of real-time results.  So you're not actually "monitoring" the 
hardware.  The data from the DCM is available only *after* you stop 
running the background process.

I just don't see how it fits.  Yes, I could do it, but then I'd end up 
with something that doesn't make any sense.  I would have to use a custom 
interface to start monitoring and then another interface to stop it.  Then 
I would query the results use the hwmon interface, but the results would 
be static.  That just seems silly.
