My wife and I tried it when we were in Chile.
We were out in a spot with about 100 vtf slopes. It was fun, but needless to say, I much preferred the riding Andes snow over Attacama sand.
The action photos in the article look pretty sweet. I'm thinking this guy is an expert tuner. We spent as much time waxing the boards as we did riding them. The wax was key for good glide. Unfortunately, with the boards we were on, the wax only held to the base through your 3rd turn... after that if felt like the worst grabby snow you could ever imagine.
