Undernet on your Smartphone
This comment on Scripting.com was quite exciting for me. Using Smartphones to implement point-to-point services using old “BBS” style technology – diallers, modems and the like.
Exceedingly easy to implement, and potentially quite powerful in its impact.
Imagine clicking a link on a web page that caused your phone to dial a number, negotiate a connection and allowed two different handsets to exchange data on a private link that was completely disconnected from the Internet?
This is a *very* cool idea.
