Has anyone written an app to transfer data through the headphone jack for P2P data sharing?
Along the lines of "I don't have network and I want to share with someone else on a different platform and don't (or can't) use bluetooth/wifi".
Narrow population, but it would be a fun project to learn about sending data over an audio medium.
Get it working well and you might even be able to send data over a set of headphones/mic, although your data throughput would likely be slow as molasses.

There was a discussion here a few months ago about using AFSK to control external hardware that spurred me to hack together a script that allows this (output only) on iOS Safari[2] and I use it to control some Arduino projects.
