Has something changed in the theory?

One would think so. That's the way it has been going in science, something new is observed and next thing you know there are papers and conferences and a new symbol appears in the equations. Quantum entanglement is sure interesting, but it is hard to work with and there aren't a lot of observations yet. It may turn out to be very valuable and make all kinds of sci-fi things possible.

Forgive me if I'm wrong, but Heisenburg simply states that you can't know both the location and the velocity of a given subatomic particle at the same time--the more accurately you pin down one, the "fuzzier" the other gets. We can still accurately detect spin just fine, so how would this affect ansible communication?

I've also never been clear on how FTL communication wrecks havok with causality. After all, if you're observing a planet ten light years away and communicate with it instantaniously, it's not like your communiques arrive there ten years ago. It's the light waves from the planet that are ten years out of date, not the planet itself. Such communication might reveal that one or the other planet is aging more quickly due to relativistic effects, but what's the problem there?
