Pretty cool. One of the big challenges in trying neutrino detection in ice is dealing with funding agencies. The optical properties of ice only get good when you are actually a few kilometers deep in very old ice. That is you can't just build a demonstrator in the nearest glacier with a few leftover photomultipliers, you need to go directly to Antarctica and bore a three kilometer hole into the ice. And projects where the MVP is quite expensive are always very hard to get funded.
