Sam Ruby points to this demonstration of "situational mashups" using IBM's DB2 v9. DB2 v9, aka "Viper", supports XPath and XQuery, and even Atom syndication.
Interesting to watch, because the demonstration is done in QEDWiki, which the speaker calls an "enterprise mashup maker".
This is similar to RSSBus, in that you can easily wire together feeds and data to create customized views of data. I like the modularity of RSSBus, in that there is no end to the potential number of operations available to its users. Data sources, application and service consumption, and output formats are open to tons of possibilities.
