Sadly, he doesn’t have a commercial version ready for market yet.
Couldn’t this be done with a small/cheap laptop? Start with a low power laptop, add a readily available battery pack and undervolt or underclock the processor to squeeze the most out of the available power (shouldn’t take too much processor power to serve up files). Slap on a USB bluetooth 2.0 adapter, shove it all into a backpack and you’re ready to test run. It’d be huge, but it’s a start.
After this, it’s just a matter of getting the software to run/synch without your intervention. Or hack a small interface somewhere easily accessible without removing the contents of the bag. Additionally, security would have to be addressed (don’t want your backpack broadcasting personal information to just anyone.)
Why carry an MP3 player when all you need are Stereo BT headphones? The backpack could have a built in MP3 player. Then, a car stereo that has a BT handsfree feature could possibly work or some sort of BT->line in adapter…
What am I missing?
