This is brilliant! a proper hack of the telephony system :) Would it be possible to send info encoded as sound? Then have a special phone/mail app on your smartphone that will get that sound and convert it to email, so you can actually read it, receive attachments, etc or even reply to it :) (Enhorabona!
