I've communicated with my friends in Turkey about Bitmessage.org and they seem to be very excited about the possibilities offered by Bitmessage in terms of private encrypted communications. Bitmessage however currently runs just on your desktop, it would be truly incredible if it could be ported to Android so that people can use it mobile and have access to encrypted communications anywhere they go.
I'm starting a bounty to port Bitmessage to Android. I would add the caveat that there should be a system added so that a person needs to log in each time they use it so that if the phone is taken by the police, they can not simply just gain acces to the phones messages (thus rendering it more a tool of incrimination). I'm not entirely sure how such a system would work, but I think that would be key to having it ported to android so that it didn't become a dangerous piece of evidence.
I start by pledging 1BTC!
