Hi Danny,
You're right--I wasn't thinking. It surely is a hack for the problem of
eliminating the embedded web server. The ideal solution is that Firefox
allows dynamic content to be served through chrome:// URLs. But I don't
think that's supported at the moment.
A better hack (a feature?) would be to add a generic protocol handler
allows Firefox extensions to serve dynamic content: dchrome://. Like
chrome:// URLs, dchrome:// URLs work only withint Firefox and is
automatically routed to the right extensions. Each extension wanting to
serve dynamic content registers something with the protocol handler. So,
for our purpose, instead of
http://localhost:1978/piggy-bank?...
we'll have
dchrome://piggy-bank/...
Hmm... that does look more like a feature than a hack to me...

Although dchrome:// will probably solve our problem, I think there's
value to ask whether we need a new protocol and what it should be. I
think there are already ways for accessing triplestores. So perhaps this
protocol should focus on a higher level of abstraction, such as trust,
storage policies, sharing policies, etc.

I've updated the developer's guide page. As for your HSQL DB question, I
got the driver from
http://scam.sourceforge.net/bin/
and adapted it for the latest Jena download.
Thanks,
