Still no luck on reporting via web services. You can do the basics in many packages, but if you want to hook into a web service with WS-Security then you need to "roll your own" provider.

I'm actually looking at SQL Reporting Services 2005 for it at the moment, since it also features the ability to provide "data models" to users allowing them to do ad-hoc queries from an understandable (in theory) representation of the business data and doesn't require them to understand SQL or web services or whatever the underlying data source is.

I know it's proprietary, but I don't have a suitable alternative at the moment, and it's actually a nicely featured product. Now to see if I can actually get it to work!
