Thanks, but what I’m really looking for is insights around the data transport, although I do understand what you’re saying about using a third-party service like Twitter. Perhaps there are services already designed for such stuff?
(BTW, this has absolutely NOTHING to do with things like free food offers. It’s just an example I came up with that has similar dynamics to the actual problem I’m addressing.)

Are these sorts of concerns things that anybody even worries about these days? (Ie., that bandwidth is becoming so cheap and plentiful that it’s just not much of a concern down the road.)

That would ping back and everything in "range" would be tagged and made available in the apps offer screen. With a single notification of offers in your area. I would not suggest using another service as your transport as that can get your Data banned.
