It won't work eh? (Score 1)

Look at the way P2P works at this moment, it looks like a true non-centralized system won't be reliable enough for grandma in Alberta to voice conference and exchange files with Grandson in South Africa for a real long time (60 years).

Big problems include recognizing resources of such a network is not merely nodes, but more.

• Directory services: It's upkeeping and serving of phone number/profile/quality of service/billing/geomatic information. In Engrish: you need a directory that doesn't suck. You can't just stick on LDAP and pray.
  
  
• Serving dark backbones: Telco is not goign to let you piggy back on their end nodes for no apparant reason, you can either tunnel everything over encrypted channels or leave it in the open. Open communication will just be chopped off by the telco using federal or state laws, even colleges have to follow these laws. The routers that route will not route these data without a fight. That leaves dark backbones. There are already too few of these to speak of, and you can go around town digging up tunnels for "community service".
  
  
• Encryption, the way we use telephones is private 1 to 1 or 1:some conference calls or the rare IP multicasting. Basically in IP geek speak you are talking billions of VPNs or secure sessions created and destroyed on the fly and you can't do this until every 802.11 can do this in a way that 1) works with that mythical directory services that doesn't exist 2) works in a way that backdoors current legislation..
  
  
• And a billion more reasons you can't do this now..
  
  

At best you'll see this in some semblance of usability in 13 years at 3 cities in Japan, and 4 regions smaller than 10 miles wide somewhere in California and Washington State.
