That's interesting, but display name makes more sense than user name if we have a service that does not use a centralized server.

You should put more screenshots so we can see what we're downloading.

Very cool. Been looking at adding chat discovery into a BLE (iBeacon) app I've working on. Any idea how it discovers other devices and establishes a connection?

Excuse my wild imagination, but is it a good app to pick up girls/guys in your library or whatever?

Cool idea, but the 100 feet line of sight requirement is kind of restrictive. Granted it uses low power BT, I'd still prefer if it was geolocation based.

Looks similar to FireChat (https://itunes.apple.com/us/app/firechat/id719829352), using mesh network technology (according to news reports, not app description).

While the chat function is maybe more of a tech demo, it could be used in places with bad network coverage or at big events where the network is gone down for whatever reason. Also interesting for geolocated services, because you don't have to send your position to a central entity, so interesting for some privacy concepts.
