USE THE CLOUD !
Big server + reliable network + light interfaces

BUT IT DOES NOT ALWAYS WORK ...
5B people do not have reliable Internet accessBig servers are not widely accessible eitherApplication specific -> beware of data-silosNo P2P dialogue, even for P2P activitiesTransfer ownership of dataSmart phones are an exception, not a norm
So we need somethi ng else....

BASIC COMPONENT: BRIDGES

BASIC COMPONENT: GLOBAL SERVER
Aggregates the content from the BridgesExposes the knowledge base to the outside world
Needs to scale up

USE-CASE 1 : SOCIAL NETWORKING
Contributors: someone's laptop, contribute one profile
Bridges: coffee-room device, keep track of visitors
Global server: server providing an overview of the contacts
=> Everyone visiting a university can connect with those whocame before and those who are there
=> Automatic, gossip-like, update of profiles
=> Tune bridges connections based on shared interests
=> LinkedIn like endorsement by resource description

USE-CASE 2 : MARKET PLACE
Contributors: farmer selling point, announces prices
Bridges: Sneakernet (people/truck/...), makes the info move
Global server: crowd-sourcing for governments
=> Very pervasive way to communicate market prices asstructured data and do crowd sourcing
=> Adjust bridges to connect to any other bridges
