Yes, very interesting.  I wonder how do you achieve full scale
software testing for a mesh networking platform efficiently?

The Serval people do physical testing in the lab and
the field. Of course, their scale is very small. You'd want 
to push most traffic through regular IPv6 Internet and 
only everything else through the mesh which doesn't
have direct line of sight or fiber connectivity.

This can be impemented as an abstract layer presenting
a unified view, which uses VPN tunnels (each router node
would not need to maintain many, even modest connectivites
would result in very few hops) over IPv6 Internet 
just as Tor or I2P do it today. The penalty would be not
that bad, given that you're not doing any deliberate
traffic remixing/onion routing.

You can prototype something like that quite easily based
on CyanogenMod with IPv6, OpenVPN or tinc, gpsd, Serval, 
(maybe cjdns https://raw.github.com/cjdelisle/cjdns/master/rfcs/Whitepaper.md
as well?) and some glue to tie it all together.
 
Do any of the virtual machine monitors  Xen, KVM, etc
support an emulated 802.11n/other radio device  that allows you to
configure  "Emulated location and geography" for each virtual node,
to test various protocols and implementations across p2p wireless
meshes  by simulating realistic connectivity performance?

Very good point. I'm not aware of simulators which can do
that on a very large scale (millions, billions to trillions 
of nodes).
