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

[Javier Simó <[e-mail]>]

I feel very much interested by DTN and I have always been supportive in 
including DTN as a strategic technology in this field, but I cannot 
contribute with personal experiences. In my humble opinion, there are 
many scenarios where communities are artificially choosing between 
having full connectivity or no connectivity at all, while there is a 
very interesting alternative in the middle that has not been explored 
enough.

I can imagine many interesting applications in emergency communications, 
in remote areas, ... just there are other people in the list better 
placed to talk about it.

Best
Javier
