Hi Don,

I've updated the demo web page with information on this error. To try out 
the demo, you need to allow my web site (thefigtrees.net) the privilege to 
read data on other web sites (in this case, sparql.org). To do this, 
follow these instructions:

Failed to get privilege ?UniversalBrowserRead to open ...

    * Firefox security won't in general let a script from a given DNS 
domain (like www.thefigtrees.net) read web data from a different domain. 
To change this,
         1. Type into the main browser URI bar "about:config" and hit 
return to get to the config page.
         2. Scroll down to the line which says 
signed.applets.codebase_principal_support ... user set ... boolean .. 
false and double-click it to change it to 'true'.
         3. Go back to the web page, and try again. When the browser asks 
you whether to allow the script to access arbitrary web pages, agree. You 
probably want to check the "remember the answer this question" box.

      Note that this is reducing the security of your browser. You end up 
allowing any web page on the site to read data from the web, which could 
include data from inside your firewall.

These instructions are copied from 
http://esw.w3.org/topic/SparqlCalendarDemoUsage . Note that you are not 
granting this privilege for all websites -- the configuration change 
simply makes Firefox prompt you when a website requests the privilege 
(rather than denying it out of hand).

In any case, I'd love it if you tried these steps and then gave the demo 
another shot.
