We'll we may give it a shot but there's always plenty of room for help..
thanks

Oh, ok. Now I see where you are going. As far as I am aware no one is
doing that specifically. At one point I was thinking of expanding my PLM
work in that direction, but other things got in the way and it is very
very unlikely I'll ever get to it.

Best,

Ben
