*"You know,  this has got me to thinking.  Has anyone worked out a system where both eyes will move without dialing each individually?"*

A couple of ways, that I know of.
Lesbently has a thread on Cr2 and pz2 scripting. The both eye dials.
The other way is to use sphere props parented to a cube and the eyes pointed at the spheres.As in the posted image.

That is what your asking? or did I miss the question. 

"in the app's you all are using Max,LW,Modo or any other app also.

Can you model on a mesh that is rigged and bent."

Modo does not have rigging. It uses morphs and a thing called the Flex Tool that lets you bend like you want. So, yes you can model a mesh on a posed figure.
