Human scale teleportation I don't see on the near horizon - in fact, I think we will have replicators before we can teleport people. There are just far too many issues with teleportation, like the rotational velocity of the planet you're teleporting to or from being out of sync with the rotational velocity of the place you are teleporting to.
Only if you're considering site-to-site teleportation. These concerns may not be relevant in a technology that teleports between two locations that are linked by a wire, for example. Then you merely need to transport the matter from one "pad" to the other, and at that point it doesn't matter where the pads are in relation to each other. This could even be extensible to wireless teleportation in which a transmitter/receiver acts as the transport medium.
But if you're talking about beaming down to a random planet, then yes, I agree that would be a little tough to do without working out the geometries.
If you didn't have to work so hard, you'd have more time to be depressed.
