This seems straightforward enough. Adding the query string parameter should do the trick. I'll give it a try and see if it works as expected.

Okay, let me think this through. I think I need to use both the @future annotation and the Schedulable interface to get this done correctly.

I'm a bit unsure about this one. I know SOAP messages have an envelope and a body, but I can't recall if there's a header or footer as well. I'll have to think it through step-by-step.
