There may indeed be a relationship between the speed of light and a computational limit principle. This is not nonsensical at all since we do not have a clear idea of what spacetime really is, all bets are really off. If the ideas of quantum measurement apply also to spacetime, then we indeed may be left with a system where spacetime (as well as the events we see play upon it) is a construction by the observer from information received over finite time periods and in finite amounts. There would be then statistical uncertainties which should limit speeds in some contexts, since the observer cannot perceive objects traveling faster than the rate at which he/she can obsderve space itself. Traveling faster than light might be like trying to have your cake and eat it too...you wouldn't be able to observe a faster than light object because you would not have the time to create the space backdrop from information received. Now there might be very intersting loopholes to this idea which could allow FTL in certain circumstances. The more we understand this, the better chance there is to investigate them. A recent very interesting paper published a few years back did indeed find a speed limit for propagation of information within networks regardless of the speed of node-to-node transmission.
