It's not a proposal yet without a decoder, it's just an idea. FSK modems microphone-channel (terrible multipath) is quite challenging and several other parties have tried to do bitcoin info over audio in the past without success. It's very interesting, but I think you do need to go through and get the whole thing working to really gauge viability.
