It has recently been announced that Virtuoso has gone open source.
Here is a weblog announcement: Virtuoso is Officially Open Source! (Kingsley Idehen's Weblog).
This is a detailed history of how the product has evolved: oWiki | Main.VOSHistory
I first heard of this announcement via Jon Udell's A conversation with Kingsley Idehen announcing a podcast interview with Kingsley Idehen, and indeed I'd heard of the prodct becuase of Jon's earlier postings dating back to 2002.
