Alternative representations of Sobolev space
Aha! I have regained my account! So the answer is yes, and I can send you a preprint if you are interested to the development. I perfectly well understand what you are saying, and the notion is quite interesting.

variational characterization of the average of an $L^p$ function
Try taking the derivative of $f(c):=\int_\Omega uc^p\;d\mu$, and then think about justifying it later (dominated convergence, etc). Then you can see why $c$ should be the average of $u$ when $p=2$, and what you might expect otherwise.

A suitable Sobolevtype space
In general, the $L^\infty$ norm can be controlled by the Sobolev norm within the right parameters, but the converse cannot be true. Sobolev functions have some nice properties of the derivatives, but $L^\infty$ (even continuous, H$\"o$lder continuous) can have pathologically bad derivatives.

Finding a good ordering of $\mathbb{Q}$
Thanks for the reference Sean. What I want to prove is false! Great to know now :)
