|Subject:||And then this will become the hugest P2P network|
When millions of users will have Desktop.google.com installed, Google will simply release a new version in which the user can check a box and say "Share the files in my disk" (maybe only files in a certain directory). This will create in a second an enormous P2P (peer-to-peer) network, in which you can search for files directly on other users' disks.
