While this research does show some promise, it's unlikely it will ever produce the H. G. Wells kind of invisibility seen in fiction. We're not actually talking about turning something invisible, but about surrounding it with a material that bends light around it. If that material were in something like a cloak or suit, it would probably move around too much to create a consistent bending effect. You'd get too many distortions and aberrations of the diverted light. Also, just because this can work on a few different wavelengths at once doesn't necessarily mean it can be extrapolated to something that can handle the entire visible spectrum at once.
The media always play up the sensationalist sci-fi ideas in reports like this, but realistically, the applications are likely to be more mundane -- things like making buildings and overpasses "transparent" to cell phone signals, cooling structures by shunting infrared around them, stuff that's practical and useful but not sexy or exciting or scary. Maybe, say, it could be used to coat the pillars in a sports stadium so that people sitting behind them could see through them. It might potentially allow some degree of stealth for aircraft, but never across the whole EM spectrum at once -- if it were stealthed against radar, it would probably be perfectly visible to the naked eye, and vice-versa, because the wavelengths are so different that you'd need structures on wholly different scales to pull it off.
