Hi Ivan,

yes, we are just in the process of buying a server on which we can host the
library. The idea is to set it up in a way that all clients share the same
RDF cache on the server. This would mean that by people using the service,
the cache up would fill with large parts of the Semantic Web (and we would
become the Google of the Semantic Web ;-). Beside of the SPARQL interface,
we are also thinking about providing a RDF browser/visualizer on the server.
People could use the browser to view their RDF files (maybe with a nice
Fresnel rendering). The browser would allow us to collect the URLs of RDF
files on the Web and could be a smart alternative to registration services
like Ping the Semantic Web. 

So, lots of interesting stuff to do and comments highly welcome.

Cheers

Chris
