I too am very interested in true Peer to Peer radio communication between gPhones - no intermediary (cellular) necessary. It seems to me that much opportunity is to be found "at the edge" of the "pay" Internet, I refer to them as F2F (face to face) applications.
For example, the ability to synchronize my phone's photos with my wife's just by walking into the same room, and by extension, either of us going near our home computer.
I am not sure what applications you have in mind, but for me, the world is wide open, as the price of F2F is the price of charging a battery.
I am not sure what to call this form of communication, perhaps it is mesh networking?

Thanks for the good ideas, everyone :) I'll probably use a combination of the above methods to write the program. Best of luck with your endeavors as well!

Without using bluetooth or (maybe) wifi, you'll need to broadcast your position to a server that can then derive proximity. Anything with a granularity of less than 10 seconds is going to be tough, you're going to have a connection open constantly. To communicate phone-to-phone without xmpp or sms, you'll need to roll your own socket based communication (should be tons of java libs available for that).
I couldn't tell you where I saw it, but I remember seeing something recently about bundling location data along with xmpp messages... you may want to search for that.

Hi,
I'd like to create a program that takes advantage of a presence concept. That is, when two phones with my program are in physical proximity, I'd like them to be able to 'see' each other. This is a little different from the presence included in xmpp, which will tell me if a friend (possibly halfway around the world) is online. Unfortunately, my searches through the FAQs and discussions haven't uncovered anything related to this topic - is a service like this already provided? If not, does Android provide me with sufficient access to the phone where I could create a service to implement this? I'm looking for something similar to the way wireless network discovery works for computers, I guess.
I'd also like to send messages between the proximate phones in a direct,peer-to-peerfashion rather than going through the normal (and probably more expensive) infrastructure of sms or xmpp. I can think of reasons why this functionality might have been intentionally excluded, but on the chance that something like this is possible it'd be nice to know how. Seeing other phones doesn't do much good unless I can talk to them, too :)
Thanks for your time. -Aaron.- Hide quoted text -
