" RSSBus is a Really Simple Service Bus that uses the RSS protocol as the main interchange mechanism. RSS is an extensible protocol used to exchange Feeds of Items. Normally these are news items or blog postings, but they don't have to be: RSS Feeds may be augmented through standard RSS extensions to exchange any type of data." (RSSBus)

An enterprise bus system simplifies the issue of data integration. I am investigating this style of data distribution in a project right now that requires multiple application data integration.
