  1kb is approx 7 full length tweets or text messages, so
  sounds good to
  me.


Actually, with SMAC, our open-source tweet-compressor, it is
between 12 and 20 full length tweets, depending on their
composition.  That said, adding in our authentication and
meta-data headers, it probably falls back to about 5 - 8
authenticated tweets per kilo-byte.

  Is there any repeater functionality that would extend
  messages beyond
  10' as the people/phones move locations?


This would be an automatic consequence of the Rhizome protocol,
which stores and forwards.  The prioritisation algorithm would
likely need some tweaking, and I am sure there are other
surprises that would have to be dealt with to make it all work
efficiently over many hops, which are challenges that I hope we
get the chance to face.



Great to hear... btw, I just realized we can use the WifiDirect
service discovery capability to send much longer data than the
current SSID/name method allows:

Not sure what the limits are, but it doesn't require you to
connect or join to be able to broadcast/listen for this info.
