It appears it's no longer worth the effort to sell this, as I have already spent more hours dealing with Orbolt then actually writing the damn thing, so it's free now… pending Orbolt's review of my price change of course.

Thanks Thomas! Appreciate it. Orbolt strikes me as something that was a great idea, but not executed so well.
