Two years ago in Australia scientists reported the first successful teleporting of a laser beam encoded with data from one location to another. There is a small downside, it basically involves making a copy which is then transported at the cost of 'losing' the original.

It occurs to me that if we should ever get to the unlikely stage of transporting atoms and then people it is not entirely a thing to be welcomed and that some method would be necessary to prevent unwanted intrusions. Long (and purposefully) lost relatives dropping in at awkward moments, spelling obsessives suddenly appearing over your shoulder and refusing to leave until you'd edited and re-posted your thread.
A wave of unexplained disappearances of confectionary and only the faintest hint of Catsan in the air to give a clue as to who may have took it. Dedicated thread followers will know that the cow with the parasol is far too busy trying to find new batteries for its flashlight at the outer ring of the Galaxy to appear in this post.
So given this glimpse into tomorrow's world now that teleporting is a reality - what price a firewall ?
Oh yeh nearly forgot about Old Crab (sorry) for OC it wouldn't be an issue - he'd use a scuttlecraft
