How many people are boycotting the Kindle because the lending feature is broken?
How fast would I get sued if I made a magical piece of software that allowed people to lend digital music purchases to their friends in some hypothetical way exactly analogous to lending them a physical CD (i.e., only one copy ever exists)?
How fast is the RIAA lawyering up over Amazon et al offering services where I can store my music in their cloud and stream it to myself?
Really, I don't think I'm making a hugely strong claim here.
