Von Braun had his rockets, Asimov the three laws of robotics... I've got into teleportation. Partly this is because I live in a city that's rated as one of the worst in the world for commuting in. Partly it's because I'm a big fan of public transportation.
Partly it's because I wish humans would think things through better before they go off and build. Teleportation technology is in its infancy now; now is the time to think the ethics through.
The biggest technological constraint you'll see in these stories is that I decided to go with an engineering solution closer to what was depicted in The Fly than in Star Trek. The teleportation system has dedicated arrival and departure pads — you can't just teleport off to anywhere you have the "co-ordinates" for, and you can't arrive and depart from the same pads (although in terms of practical construction, they tend to be built right next to each other in the stories).
You can use this list to read through the stories, or filter on the teleportation label.
