Proposal: Distributed audiobook of US Constitution?

Following up on this earlier Boingboing post about a downloadable Constitution for your iPod, the EFF's Jason Schultz says, "How cool would it to start an audio project having famous lawyers/judges reading various parts of the U.S. Constitution for download, similar to the distributed audio project for Lessig's latest book?"

Other than the idea of voluntarily listening to lawyers speak, this sounds like a great idea to me, too. Has this been done before? No? Any takers?
