Thanks Greg L, this is very interesting indeed. I've passed your article link onto the other guys who are more deeply into SQL internals so they can investigate.
I now have to investigate Hoss' hint that I can programmatically invoke SSRS reports via a web service. I have a 27MB 770 page PDF book titled Applied Microsoft SQL Server 2008 Reporting Services by Teo Lachev. Chapter 15 is titled Reporting for .NET Clients, so maybe some good news for us will be in there. If I find anything startling or useful at the end of this research I'll let you all know. Greg K
