Interesting idea, always nice to see new ways to brew coffee. I wonder how easy it is to replicate their process? The article isn't hugely clear. It talks about using a modified off the shelf domestic espresso machine but the picture at the top looks like a custom built device with potential complex machining involved to build.
If it's the case you can buy an ultrasonic transducer and bodge it into an espresso machine lots of fun possibilities for coffee geeks (and to my point above someone like James Hoffman will give it a go and build up a bunch of interest in the technique)
If it's the case you need a bunch of complex machining and significant technical skills (say those possessed by chemical engineers conducting cutting edge research...) then I imagine this will struggle to go anywhere.
