Technokitten:

But you know what, bluecasting will be an interim technology at best. At some point in the near distant future, we will be always on on our mobiles with wap access, flat rate data charges, pre-installed QR code readers and phones that just work. In that scenario, we won't need bluetooth to file share, we'll just do it over the air, like we do from our PCs. We'll take a picture of a QRcode, it will link us to the wapsite and we'll download away to our heart's content and maybe even share with a friend via the 'send to a friend's phone' link.

Especially with 1 billion mobile broadband users in 2009 (see post below).
