One could much broader (and more precise) and say that we've never seen information (in the abstract sense, which covers everything) exceed the speed of light. Ever. Which is what the rule really says.
The speed of light is an extremely tough problem. One that has the potential to be uncrackable because it is far more fundamental than most people realize (particularly when properly re-phrased as the "speed of information"). Saying that there is a way around everything in nature is almost as naive as saying there is no way to emulate everything found in nature.
Still doesn't mean hyperlight travel can't be done...
