You may know what this is about, although it’s unlikely. This goes back to some very old stuff to do with a thing called Capers. This was a project that was to create an alternative OS for Palm devices that was purely for music. It never came about sadly, although there were some demo applets that you can still find if you’re really interested.
I feel that now is probably the time to let go of this and stop wishing that they would come about. It isn’t going to happen I don’t think. Still a shame!
