Teleportation --will pay double for the service.
you know all those random pixels you get in a fax or even a scan? Yeah. Do that to your brain. Or, more particularly, the wall of a high pressure artery, in your brain.
I think teleportation will have to be an analog technology instead of a digital one.
By analog I mean manipulation of space/time fabric that you actually step through, as opposed to being scanned and reconstructed on the other side.
