Good article, always handy to see alternative methods.

I built a C# console app that renders the reports via the webservice. Once I got my head around the .Net stuff is was relatively easy to put together.

The app takes a stored procedure name as one of its parameters and this stored procedure returns a DataReader which is used to drive the report rendering.

One of the nice features of rendering via the webservice is that the same report can be rendered in any of the registered Reporting services formats and you can have 0-n parameters for the report.
