publish subscribe redux...

I remember, around 10 years ago, first reading some of the documents describing Old Mutuals hub-and-spoke architecture including the publish-subscribe pattern. Later i did bits of application programming using the developed infrastructure to collect information from disparate source information repositories. This was MQSI, before it was all rebranded into the Websphere product family.
Fast forward to the 2009 Tech Crunchie award nominees. This slideshow outlines one of the entries, PubSubHubbub.



Here's the project.
