BI and Self Service Reporting Tools that Support Web (HTML) Interface? Hopefully a simple question.  What BI tools (commercial or OSS) support self-service reporting or self-service BI via an HTML web interface?

I specified HTML because I know of at least one that can do it via the web, but only in Silverlight.
Pentaho. 

There's Jaspersoft too, but I found Pentaho a little more useful, though Japser is prettier.
