Has happened to a number of instruments. http://amzn.com/B003UHLH0C

There should be an opportunity here for leasing non-digital pianos, given some technical solution that solves the transportation problem. (Perhaps something like a PODS transporter? Composite frame?) The size of the disposal problem is a big pain point.

Carbon fiber composite pianos might represent a significant advance. Such composites are stiff enough to avoid much of the "settling" of a metal and wood structure under such immense compression and cantilever loads. (Carbon fiber composites are so stiff, they caused Boeing some problems with their newest plane. Instead of tolerances resulting in the gradual bending and settling of metal parts into place, the slightly mismatched carbon fiber parts maintained their stresses.) This property would significantly reduce the labor costs of tuning.
