[guardian-dev] Gilgamesh, FireChat etc

[Hans-Christoph Steiner]

It seems that the most promising use case for gilgamesh is for data
transmission as people walk by each other, etc. in public spaces.  There is
probably a lot to learn from similar projects that were built around this same
idea.

One that comes to mind that was a hot topic in 2007 is providing rural
internet access by putting local wifi boxes in buses.  At bus stops, there is
another wifi box, so when the buses stop, the two exchange data.  Its a kind
of newsgroup/UUCP system.  It was set up by technicians, so if we found them,
I imagine they'd have a lot to say about how to get drive-by data systems working.

Here's an article about it:

The organization is apparently based in Cambridge, MA, maybe you could say
