Matra to open source their CAD component library

Matra DataVision has decided to LGPL a set of components that currently earns 3.5 million dollars a year, cost 75 million dollars to develop and has been sold since 1995. Why? Because they hope to sell services to the scientific market that currently uses its own proprietary technology rather than commercially sold components -- a market they value at 450 million dollars. Where's the source? It will be available from opencascade.org on December 20th. Commercial support is at opencascade.com. Some screenshots are available.
