None taken ;) I really just want to use the opportunity to a) get
Brandon up and running and b) fix any short-comings on sqm-scripts on the way.

I fully agree.

You are spot on, both are rather exotic test cases at least as far as
reports go; that is what intrigues me even more ;)

I guess since we just thought sqm-scripts to allow verbose debugging
output (into a log file) I thought it is time to advertise that feature ;)

Oh, you had mentioned that already and I fully agree that getting a
simple test cases going is going to help a lot. So we violently agree ;)

Again, I fully agree, I guess I should have mentioned that I have no
genuinely new advice but rather just recommendations for slight variations on
the way. Sorry for muddying the water here.
