Microsoft to do for Usenet what it did for Email & The Web?

Netscan is an interesting NNTP based project and it is pretty much along the same lines of what Virtuoso has provided (albeit with an inferior UI) for NNTP since 1999.

Using Virtuoso the data presented by Netscan could very easily be presented as XML which could then be further processed using XPath, XQuery, and XSL-T with the final result RDF (since this is metadata afterall - another contribution to the Semantic Web)
