On the bluetooth front, you might want to look at Katherine Moriwaki
and Jonah Brucker-Cohen's work on "circumstantial networks" --
www.kakirine.com. Also check out Timo Arnall's very useful list of
"mobile social software" projects. Some of them may be relevant to
what you're interested in: http://www.elasticspace.com/2004/06/mobile-
As Eric said, bluetooth outside of a very short range is impractical,
but you may want to look at the academic work done on "data
mules" (evocative name, that) which are digital devices that work
within delay-tolerant networks (often called DTNs) to relay data
whenever possible to gradually get the data towards a destination.
They include wifi nodes, short-range wireless networks (like
bluetooth). See: http://www.dtnrg.org/wiki/About for examples.
