Re: [gaia] draft-irtf-gaia-alternative-network-deployments. Stephen Farrel's comment #1. DTN

[Joerg Ott <[e-mail]>]

Two data points:

Within the RIFE project: https://rife-project.eu
Here, we use DTN as on local dissemination strategy to reach less well
connected users.

We build small things like the liberouter: www.liberouter.mobi
We think that this is a suitable model for localized networking
(understanding that global information access is important, but it's
not everything).  We spent some time with a student project course
looking at self sustainability of such systems from an energy 
perspective.  More left to do.
