Whoa! And I though Reporting Services was cool as is...
So by now, I think everybody gets the architecture behind Reporting Services (RS): You have a web server that uses tempates (RDLs), MetaData (from the Reporting Services Database) , Report Data from basically whatever Data Source you can reach with OleDb or ODBC and a Transformation Engine (the RS Service itself).
That's great if you want to develop Web hosted reports.
That's not so great if you want to develop reports without using a Web Server.
At least until Beta2 for Visual Studio 2005, where we should have controls that will give us query, rendering, print and print from a WinForm (and maybe a Webform) client without the need for a Reporting Services Server! How cool is that?
Kudos the Reporting Services (yet again) and thanks to Euan Garden for the 411 (yet again)
