Open source publish and subscribe

Or view presentation on the Pubsubhubbub website.

Subscribe to anything, whether RSS or Atom feed, or custom syndication, with Pubsubhubbub. According to the Google Code website where it is hosted as an open source project, PubsubHubbub is a

server-to-server web-hook-based pubsub (publish/subscribe) protocol as an extension to Atom and RSS. Parties (servers) speaking the PubSubHubbub protocol can get near-instant notifications (via webhook callbacks) when a topic (feed URL) they're interested in is updated.

Publish and subscribe at Microsoft

What is PubSub on Microsoft Codeplex? Is that a version of PubsubHubbub implemented successsfully for Microsoft internal usage? It is active as of November 2011.

I think this is more likely: PubSubHubbub is a specific case of a web-hook based publish/ subscribe protocol. Microsoft's PubSub is another specific case of the protocol. It might be different or the same.
