Imagine Cup Winners Announced

Love it !
Bye Bye FolderShare (at least when this P2P will be activated) because I still cann't select 'don't sync with this device' with live desktop)
From my testing here with the new bits, it is not sending directly over the LAN yet.
Live Mesh's pub/sub model is conceptually a push model -- each device has a notification queue, the device can create subscriptions, and when a subscription generates an event (or another device or part of the Mesh needs to reach the device), that event is posted to the queue and the device gets it.
Because Live Mesh is designed to work across any network topology, we can't always ensure that the cloud will be able to push a notification down to an arbitrary client -- it might be behind a firewall, or NAT, or who knows what. So instead, we have each client open up a single long-lived HTTP connection to the server. If there are no new notifications, the request times out after 60 seconds, and then the client opens a new one. When a new notification comes in, the cloud sends down in response to that open request from the client. You might have heard this technique referred to as Comet or full-duplex AJAX.
