This thread, /viewtopic.php?f=2&t=101936, introduces how WIDesigner can help whistle and flute makers. We're at work on support for reed instruments. As a sample, it can predict the playing frequencies of a smallpipe chanter about as accurately as I can measure them.
As you (and Benoit) are well aware, there are still trials and adjustments involved, but it could at least give you an idea where to start drilling finger holes.
PM me if you're interested.
