Another practical problem you would likely have, with any method, is unequal cooling.  I bet you would get ice chunks on the inner wall of the can with warm beer in the middle and you cant really stir or shake the beer.

general stuff, but...pressure and temperature are proportional, that is a change in pressure brings a change in temperature. the problem is when air leaves the compressor its already back at atmospheric pressure and you've missed the boat.

Have you ever felt the gas coming out of a compressed tank? It's extremely cold. You can freeze things with it.
