I don't know enough about the current state of the research and the physics underlying it to comment intelligently on those questions (causality & the uncertainty principle) as they're relevant here. But they are very good questions!

Well, here's something to consider...if superluminal transportation of information is possible, why hasn't anyone sent us messages from the future?

For instance, someone could send himself winning lottery numbers from the future...and I'm guessing that guy in West Virginia is not a physicist.

Or...maybe they have sent messages from the future...and we just haven't been told about them! </tinfoil>
