Nothing revolutionary, but someone had to do it. (Of course, you would take something expensive in software and implement the logic in software. Of course you can get by implementing only the most common requests: GETs to a small subset of keys.) I don't intend to criticize this paper in particular, but, generally, I don't see small performance improvements in such software to be very useful for society. Academia just becomes a research arm of corporations that might even be a net negative for society: eroding privacy rights (Facebook et al) or introducing volatility into stock markets (HFT could use this paper's insight just as fruitfully.)
