[dundee] Servers in my pocket (SIMP) and DTNs

[Robert Ladyman]

Happy New Year to those of you who are celebrating a New Year...

Many thanks to those who came to the "No Such Thing..." talk.

I was thinking more about what could be done with in-pocket (on-phone) 
servers, other than the identity / location stuff: I was reading an article 
about how Syria had just re-enabled its disconnected internetworking 
connection and also recalled what happened in Egypt, etc. - what might be 
called 'challenged' networks - and that lead me to think about a 
disconnected, store-and-forward network where, for instance, [encrypted] 
messages are passed 'hand-to-hand' (or pocket-server to pocket-server) until 
a fully networked connection is reached... if at all necessary (local 
dissemination might be enough).

Unsurprisingly, I can remember the old FIDONET and UUCP stuff and started 
looking at them, coming across "Delay-Tolerant Networking", including a paper 
co-authored by our old friend Vint Cerf:

...and an interesting powerpoint with an Interplanetary Network model

One could picture visiting a coffee shop, your SIMP picking up a message or 
two; travelling to a bus station, where they are passed on to others' 
SIMPS ...and so on.

Regards,
