Personally I believe that to go faster than the speed of light you would drag space-time/aether with you and that the bubble you carry with you would tend to disconnect to a degree from that of the interstellar ambient causing a barrier/shield effect and it may not be too dissimilar to the loosely defined hyperspace or warp from scifi.
This should maybe deal to issues of interstellar radiation and the interstellar dust. There is not a total absence of evidence for something like this occurring in experiments or in nature occasionally.
