Tachyons, man we got tachyons and lots of them!

What about trana-finite computation vis vis higher physical dimensions? Kind of like two recent books by Rudy Rucker (Saucer Wisdom) and Clifford Pickover (Surfing Hyperspace). Because one physical dimension overlays another, the distances between components and storage media is not an issue. Sphere packing made easy.
