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 :-)
