I hate to burst your bubble, but this is an effect requiring magic
geometry. It might be good (perhaps excellent) for switching (where a
state has to influence other state nearby, quickly (intuitively,
slightly tweaking the wavefunction nearby an electron outlet in
ballistic circuits should have a large impact)), but this is no way to
communicate things over noticeable distances.

If you don't have an agent swarm, good old packet switched network
over a bus grid will do just fine. Gradients, baton estafette,
acoustics/photonics don't make much sense there.

Er, and could you kindly switch off the HTML default in your browser?
(And maybe also check the box with 72 chars/line). It is quite
annoying otherwise.
