Adam,
I download all of the LetsTalkBitcoin podcasts via the iPhone Downcast app.
Downcast and other podcast apps allow you to enter login credentials on a per feed basis, mostly for premium / protected podcast feeds. You could use this credentials feature to keep track of who is downloading LTB podcasts for purposes of issuing LTBCoin. The login username would be the LTBCoin address of the user. That way, you'd be able to account for who downloads and when.
Thanks for considering. And, thanks for all the great podcast content!
-Paul
