I'm curious about how this actually works, geometrically. Example: A B C Those are three people. Imagine each segment is 1 mile long. So A can see B; B can see C; but A can't see C. If B and C are having a conversation, does A see B talking to someone who effectively does not exist?

turns out you're right. anybody have suggestions on how to fix this?

Why not group people into free-form clusters based on user density? So, if you have 5 people that are effectively in the same building, and 3 people that are outside of it in various directions, group those 3 into the 5. This has the effect of forming virtual chat rooms that come and go.

Not sure what you're using on the backend, but if it's PostGIS... here you go: http://gis.stackexchange.com/questions/11567/spatial-cluster...

This app clearly reminds me of the device John McAfee promised us: http://www.theverge.com/2013/9/30/4786008/john-mcafee-d-cent...

"the device [...] has a range of around three blocks. Everyone in those three blocks can then communicate with each other and that will obviously change as users move in and out of a local area."

Will definitively try to maybe see people from HN in Paris.

How about a 1 mile (square) zone, rather than 1 mile away from you? So you just cut everything up into mile-square slices, and you can talk with everyone in your slice... Concept is basically the same, but should overcome that issue.
