Hey I'm not focused on sudomesh but I like it! Can't work on stuff for it but
thought this would be fun : first time I saw someone explain mesh networks in a very easy
way.
-- rip off this graphic and do a sudomesh version
-- as an outsider I'd love to see a Mesh video round table with jenny jake and a few
random neighborhood folks. Like filmed at the omni table !
I'm busy focusing on my own things but admiring yalls from afar !

Unbreakable: Mesh networks are in your smartphone's future
It's not that we're running out of mobile bandwidth. It's just that it's
poorly distributed.
If you're in your home next to a Wi-Fi router, you might have a clean signal and
access to a 12-megabit connection. Meanwhile, someone outside your door could have a
smartphone that's struggling to hold onto a slow connection to a cellular tower a mile
away. But mesh networking might make things better for everyone.
Mesh networks let devices share their connections with other users. If one user has a
clean network connection and another nearby user does not, the second user can piggyback
on the first's, automatically. If there's a collection of many people, their
machines can all cooperate to make connections -- to each other and to the global
Internet. In advanced mesh networks, connections and data can hop among devices, creating
ad hoc bucket-brigade paths for communication.
The concept of mesh networking is not new. Many military systems rely on mesh networking,
since forces in the field cannot rely on communications infrastructures. Utilities also
use mesh networks for collecting data from equipment, like smart meters.
On this Reporters' Roundtable, I interview two innovators in mesh networking.
They're both trying to bring this liberating (they say) and bandwidth-saving (ditto)
technology to the masses.

Micha Benoliel's company, Open Garden, makes a mesh networking utility for Android
smartphones and for Windows and Mac laptops (support for iOS is coming). It's a free
app that turns your device into a mobile hot spot. No matter how you're connected to
the Net (Wi-Fi or cellular), it makes that connection shareable (over Bluetooth) to other
Open Garden users. Likewise, if you're running the product but don't have a
connection to the Net, and you're near a user who does, this service seamlessly gets
you online.
Benoliel says that, for the most part, carriers and ISPs welcome technologies that improve
bandwidth for customers and that also lower power requirements (connecting to a nearby hot
spot over Bluetooth takes a lot less power than linking to a cell tower). "The only
way to improve the wireless networks is to increase the density of microcells or hot
spots. I think carriers really understand that," he says. His pitch: "We turn
every device into a hot spot... and we improve the network itself."
Sri Srikrishna was the founding CTO of the mesh networking company Tropos (recently
acquired by ABB), and is now working on bringing mesh technologies to populations where
today's standard wireless networking technologies are insufficient, or are blocked.
See his paper, "SocialMesh: Can Networks of Meshed Smartphones Ensure Public Access
to Twitter During an Attack?"
Srikrisha says it's time to do two things for people who don't have reliable means
to connect to the global net. First of all, we can make better, more frequency-agile
radios. Second: Mesh them together.
Hooking users together through mesh networks can also democratize communications and make
them, he believes, more robust in the face of repressive regimes that might want to shut
down the capability to reach the outside world. With a mesh network, a very small number
of users who happen to have a connection can share that with other users who don't.
"If you have a large number of these devices, no government will be able to stop
it," he says.
Srikrishna and Benoliel both claim that the global growth of smartphones -- all are
handheld computers easily capable of supporting mesh networking stacks -- should lead to a
global infrastructure shift, in which these handsets become a bigger part of the
infrastructure itself, not just clients on it.
"Can you build a network that's indestructible?" asks Srikrishna. He says
it's worth doing. "A lot of the problems in the world can be solved if you can
have UStream everywhere in the world, without being blocked."
