There are lots of customers that don't want freedom, they want speed
when used by Wall Street hired twenty-somethings with no experience,
and someone to blame if anything slows down.

Many won't opt for proprietary SW if the FOSS is good enough...

Unless it becomes the toolkit of choice for easy FOSS development and an interchange between
others will be as possible as the CSG the closed tools let out.

IGES, perhaps AMF or VRML.

But, they all seem to suck, and not get results with volunteer driven FOSS...

What is the best mech CAD interchange format today?

A ha!  I thought something like that, but was vague on the concepts.

Yeah, me too.
