This is a write-up I did on delay tolerant networking (internet that isn't necessarily real time) #330735

I've been meaning to do a write-up on how to set up a DTN router, but in the meantime, checkout the github project I would probably do that write-up with: https://github.com/dtn7/dtn7-go

And hey, do the write-up yourself :P I'd zap it.
