The comment are interesting, for example
"Silicon Valley should be able to develop an easy app to accessible at somewhere other than a bank, possibly at the post office, the library, the pharmacy, or Walmart, to allow funds to be dropped off somewhere in the US and picked up somewhere in Mexico or other countries. "
Newsflash: There already is. Bitcoin
(It's as if they are begging for bitcoin to be mentioned somewhere)
Whilst that is a valid point, we could also read it to say that Bitcoin needs to be accessible "at the post office, the library, the pharmacy, or Walmart", offline if you will.
