Microsoft Documents released by Snowden show the extent to which Microsoft helped the NSA and other security agencies in the US. "Microsoft helped the NSA to circumvent its encryption to address concerns that the agency would be unable to intercept web chats on the new portal; The agency already had pre-encryption stage access to email on, including Hotmail; The company worked with the FBI this year to allow the NSA easier access via Prism to its cloud storage service SkyDrive, which now has more than 250 million users worldwide; [...] Skype, which was bought by Microsoft in October 2011, worked with intelligence agencies last year to allow Prism to collect video of conversations as well as audio; Material collected through Prism is routinely shared with the FBI and CIA, with one NSA document describing the program as a 'team sport'." Wow. Just wow.

While I am fond of the idea of having a massive public mesh network, there are a number of impediments that would likely hold it back.

1. There are legal implications. Users who volunteer their IPs to build mesh network gateways are in danger of becoming victims of the court system (ie running open wifi).

2. On the internet IP routing is accomplished via powerful BGP routers that build routing tables by trusting the routes advertised by peers. This works as long as the peers are trustworthy (which they generally are, but things can go wrong, see However in a mesh between *untrusted/adhoc* peers, this becomes a distinct vulnerability for the mesh network.

3. Performance is an issue: bandwidth, latency, low cpu, packet loss, etc. Without centralized packet management, one hog might consume the bandwidth of everyone else in the vicinity. Realtime applications like VOIP could prove difficult.

4. Existing technology in mobile devices might not be adequate, consider that generally WiFi APs/Clients only support a single channel at a time, significantly limiting scalability. Professional mesh networks can use multiple radios simultaneously for this reason.

5. Having a mesh doesn't necessarily bring more privacy or security if packets still go through a compromised ISP. Even if traffic doesn't go through an ISP, it becomes easier than ever to perform a MITM-attack in an adhoc mesh network. Even secure encryption schemes require keys to be exchanged beforehand or the use of a CA (which can be compromised).

Don't get me wrong, I'd very much like to see a public mesh network succeed and participate on it, but I'm also skeptical as to some of the security features some people might want it to have in the context of government spying.

All of that is why I had said it was a nice idea but probably will never happen. It's interesting to theorize about though!

Even if all technical problems were solved, and we managed to get such a network to work. We would quickly see new regulations that somehow made it illegal to user or impossible in some other way
