First, both Google and Facebook are planning to provide global wireless internet. Google has been working on Project Loon for quite some time. The idea behind Loon is to launch a network of balloons that would beam internet down to base stations that would then provide local free wifi connection for all users in the area. Recently Google also purchased Titan Aerospace which makes solar powered unmanned aerial vehicles capable of staying in the air for years and also capable of beaming internet down to areas without affordable internet connection.
These companies are doing this of course to increase their user bases, but the free internet will also provide plenty of bandwidth for the tiny transactional data that Bitcoin requires to send and receive funds. In the next 12-24 month being able to send bitcoins to the middle of nowhere will become a reality.
Free wifi "everywhere", really?
...Several bitcoin cards, ATMs and POS terminals are in the works. ..
Sounds like you are making a solid case for optimism.
