Hi Antoine,

Corona is P2P because of its internal structure: a logical ring of nodes that polls websites and RSS feeds cooperatively, detects updates, and sends the updates to clients. You're right that those nodes do not include the end users. However, the end users reap the benefits of Corona's P2P internals: hundreds of nodes poll sites in a globally optimal manner to get updates to users as fast as possible without overloading the network.

We're writing to announce Corona, a new system that you can use
to monitor websites and RSS feeds through instant messages.

Corona is a peer-to-peer publish-subscribe system for the web.


I'm not sure exactly how this is a peer-to-peer system, since there is
clearly a conceptual (and actual) distinction between clients and
servers.
Moreover, end users don't seem to participate in the overlay network at
all.
Am I mistaken ?
Is it "peer-to-peer" in the same way that Akamai is ?

(apart from that, trying to solve the "RSS is a resource hog" problem is
a good idea ;-))
