That's it on b_b's cracked Nexus.
We will be testing it this week, and plan to release it the next.
Once again, big thanks to insomniasexx who helped salvage the project.
In short, Tin-Can is a one-to-many messaging app (think Twitter, alpha.app.net, etc) that does not connect to the internet or use any cellular service. Instead, messages hop directly from phone to phone over wifi. When you turn Tin-Can on, you exchange messages with other Tin-Can apps in wifi range. Messages spread like the flu. In general, it's terribly inefficient. However it should work well in high density, especially conventions, gatherings, protests, etc. Obviously, it also can't be disrupted by loss of internet or cell service. It is built for Android, and it will be free.
