Now, maybe MTF is not really the place for science, but I know for a fact that there are users really interested in these things. This technology is not really extremely new (the presentation I'm about to link you to is 4 months old), but it's simply amazing. Imagine it being used for the next generation of Hawk-Eye technology for instance. There would be no margin of error whatsoever (in any sport - not just tennis). Of course, why stop so fast when this technology could actually help us see without looking? Imagine recording a tennis match without actually buying a ticket, all from outside the arena.
