Interesting kingsley, not sure what the implication is of GPL2 is e.g. would one have to redistribute the whole source code of anything attached to it?
It just means that you keep the source code intact and share any enhancements that you make etc..
Remember, this is a client that works with CXML output. A server (e.g., what Virtuoso does) can construct a URL that resolves to the CXML that's used by the viewer. Ultimately, we are going to convert the CXML into RDF such that the whole thing runs off RDF model based structured data instead of XML specific CXML.
The hardest part of this effort (client side) was getting the HTML5 client to match the original silverlight plugin. Of course, there are other challenges on the server side which basically required the integration of image processing into our SPARQL query engine. That's a whole different topic :-)

Background: A while back, Microsoft introduced a powerful data visualization tool called Silverlight that ended up being under utilized and eventually killed off due to its delivery as a plugin. A group of us decided to get the data visualization tool ported to HTML5 [3] as part of an open source project. Deliverables: We now have an HTML5 rendition of the original PivotViewer combined with some innovations at the platform independence (works on the iPad and iPhone [4]), layout (includes tabular presentation), and data access (supports SPARQL) levels. With regards to SPARQL, an endpoint simply needs to include support for CXML as one of its output formats.
