Good question, beto. I've read that in some environments, unsheilded ICs can pick up RF interference. That's not the case in my environment, fortunately.AC's twisted pair helps reject RFI because of the twisted pair nature, just like unshielded network cabling, but it's not as foolproof as a real shield.
However, as jnorv points out, one can shield some of these designs, notably ChrisVH's and probably Audio Consulting. I'd think the anti-cables would be more difficult to shield, though not impossible.
The trick to shielding is to keep the shield as far away from the signal-carrying wires as possible. Using some form of spacer, as beto jnorv suggests, is the best way to do that.
Here's another recipe that mainly uses an air dielectric with a shield. I've not tried them, but I don't see why something like that wouldn't work with ChrisVH's design.
