Ripple (by the Grateful Dead)
======

if my words did glow 
With the gold of sunshine
and my tunes were played on the harp unstrung
would you hear my voice 
come through the music
would you hold it near 
as it were your own

its a hand me down
the thoughts are broken
perhaps 
they're better left unsung

ripple, in still water
where there is no pebble tossed
nor wind to blow.

reach out your hand, 
if your cup is empty
if your cup is full,
may be be again.

RPL, pronounced Ripple is an IETF protocol that provides connectivity among 
nodes that can not all hear each other, but rather have to form a multihop
mesh-like network.

Unless other mesh efforts, this all happens at layer-3, in IPv6
Router Solicitation messages. 

The authors thinks that once RPL-style "mesh" routing is loose on 
citizen controlled mobile devices that citizens will no longer be
held hostage to incumbent telcos that dominate the broadband
"Internet".

This set of programs, plus a test bed/simulation system is a set of tools
that runs under the Linux kernel:
  - on netbooks, 
  - laptops, and 
  - on phones like the Google Android and Nokia N800.  

Programs include:
  sunshine  - run this on root/grounded server to announce
      routes and on any other well provisioned machines.

  glow    - run this on underpowered machines that just need
      enough to join the DAG.

  pebble    - insert DIO messages into the network, run from
      the command line.

  blow    - cmd line utility to control sunshine and glow.
