Late reply but I hadn't considered that, it's an interesting problem, it might be worthwhile to just buy a second American-standard optical table, if the cost is only a few thousand dollars, and most of the money is spent on other hardware and labor, assuming this software actually saves anyone any time.

Then again, this is coming from a guy who had to call nearly every fastener supplier in a country in order to source a specific kind of countersunk UNC screw to fit foreign hardware he ordered. That still stings.
