A music project has cropped up that is very much like Project Calliope, if you swap out 'one man show' and replace it with 'crowdsourced'.  The core concept is Calliope's "convert space to music via detectors and send to ground for anyone to remix", and (perhaps due to the Tubesat design limitations) very similar in terms of approach, method and focus as well as intent.  Innovation?  Flattery?

Last week I said the mission of Calliope is that "hearing the levels and variety of activity in the ionosphere in real or near-real time, as ambient sound, will help people get an intuitive sense of the activity and change at the boundaries of space."

Part of me thinks an orchestra of orbiting music satellites, loosely coordinated, could be a great meta-experiment.
