Interesting. I'd never thought of it this way before, but I read that 1' requirement as meaning "a single hole at least 1' square". So instead of making incredibly expensive mage prisons, all that's needed is some kind of Dimensional Lock and chicken wire.
That could make for a fascinating defensive spell, too: "Summon Wire Lattice", which surrounds a targeted creature with a sphere of tighly woven wire. Spellcasters then can't target anything outside the sphere, as their Line of Sight has been broken.
I'm not sure I like where this is going.
