I was thinking about IPoAC the other day and had a horrifying realisation of it's implications: teleporting someone will involve moving enough data to reconstitute an identical human being from the sending to the recieving teleporter, and assuming storage technology grows in a similar way, there will be a point where it's faster to be downloaded to a drive, strapped to a pigeon, and flown to your destination for reconstitution than it will be to wait for the data to transfer over.
