there are now aps available for iOS devices (FireChat for iPhones and iPads) and Android devices (Open Garden for phones and tablets) that use bluetooth and the devices local wifi ability to connect directly between devices and form a local "mesh network"
This means device to device connection without going through cell towers or isp's, and multiple paths makes it faster than single source linking. Because the mesh network is dispersed onto individual devices there is no control over use by companies or governments. This is working in Hong Kong and linking the protesters together ... free exchange of information ...

free exchange of information Yes it is free... up until a tank runs over your smart phone. The situation in Hong Kong has large potential to end badly. I surely hope not.Under a government which imprisons any unjustly, the true place for a just man is also in prison.

Those who profess to favor freedom, and deprecate agitation, are men who want crops without plowing up the ground, they want rain without thunder and lightning. Frederick Douglass

There is a corner of my house where wifi reception is bad and this provides connection for my tablet when my phone is downstairs where wifi reception is good (it would likely be better if I moved the router out of the basement and into the office).
Yes it is free... up until a tank runs over your smart phone. Actually they would need to run over ALL the mesh-linked phones\tablets\laptops to shut it down. Losing a node does not cut off the linkage, unlike traditional lan and wan systems.

The problem is range - bluetooth has a range of about 10m so it'll only be any use in a crowd and where a large proportion of people in the crowd have the app on and active. I'm guessing that it's also a security nightmare.

Actually they would need to run over ALL the mesh-linked phones\tablets\laptops to shut it down. Exactly. China has lots of tanks. The tank may be on top of your phone AND you. Others can still use the network to yell "Run!!". Also jamming wifi and bluetooth is not really hi-tech.

Because we live in a crowd. You can think of a town with open mesh networks to provide internet service for all the people in the town
... I'm guessing that it's also a security nightmare. More than we currently have? Enjoy.by our ability to understand Rebel☮American☆Zen☯Deist ... to learn ... to think ... to live ... to laugh ... to share. Join the effort to solve medical problems, AIDS/HIV, Cancer and more with Team EvC! (click)

One of the basic concepts pretty much universal during the creation of the internet was unreliability. Applications and even the data packets themselves were built to work on unreliable mediums. Packets could take different paths and messages were broken up on creation and reassembled on receipt. Missing pieces were then requested from the sender to complete the message.
The mesh concept is simply an extension of that idea to include not just paths but also additional services, WiFi, Bluetooth, internet ...Anyone so limited that they can only spell a word one way is severely handicapped!

Or is the (theoretical) point to have everything connected so that the internet still exists but ISP's are not required?-wouldn't this add a huge lag if the data you were connecting to had to hop over 100's of linked devices before getting to yours? I just don't see the practical usage of it yet.But, well, all I've done is read your post too... so I am also woefully ignorant of the possibilities...

What's the goal of this? It would be useful for coordinating an event and maybe for communicating with like minded people for a short time. More of a large intranet than an internet. Kinda like those adhoc networks people used to set up at colleges to share music. But you have to assume that the government is listening in. That does place some limits on its usefulness. But even that can be overcome with some method of verification. The problem is to avoid making the added security another point of attack.

What's the goal of this? quote: Device-to-device connectivity only? I don't see this as very useful. That is, you can't see the internet. And if you use device-to-device-to-device-to-someone-with-an-internet-connection to use the internet... then doesn't that one person get charged a whole lot from the ISP's in order to supply data to all the others who are connected? I don't know how the ISP things works, but don't look at it like a chain, look at it like a mesh. There could be 10 devices with internet connections and then another 50 devices without an internet connection that are connected to the internet through the mesh network.
Or is the (theoretical) point to have everything connected so that the internet still exists but ISP's are not required? -wouldn't this add a huge lag if the data you were connecting to had to hop over 100's of linked devices before getting to yours? Perhaps, but with the mesh it is more likely that you only have to hop over 1 or 2 devices, not hundreds of them.

The goal is to add a layer on packets that determines shortest path to communicate. If you can reach a destination with Bluetooth use that path for these packets, if not Bluetooth check WiFi. If destination not available on WiFi then then use Internet.
In such a case a message to friends gets sent using Bluetooth to those immediately adjacent, WiFi to those slightly further away and packets sent over the Internet only for those not included in the first two groups. It is another step toward ubiquitous connectivity.Anyone so limited that they can only spell a word one way is severely handicapped!
