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-peer fashion 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
