And even after that, how would we use it?
Teleporting from one machine to another? The machines would probably be destroyed.

Absolute freedom as to where you will Teleport (eg. Coding in a location using the different axi and being teleported to it)? What would stop people from abusing such a system.

I can only see Teleporting being used with transferring items. Mail, delivery and so on.

I cannot really see it being used otherwise.
