Yes, this is the type of solution that The VirtualGL Project supports now. My understanding from his original message, however, was that he already was running CATIA on a local Windows workstation and was looking for a way to share the screen from that workstation. Both are useful for different reasons. There are a lot of applications which don't necessarily play into the server-side rendering model, because the data they deal with is small enough that running on a laptop connected by 100 Mbps Ethernet is sufficient. I have several friends in the SolidWorks business, for instance, and their market is primarily small shops for whom the overhead of putting in a 3D server would outweigh the benefit. However, a problem they do want to solve is how to collaborate with other users. I think that solving the problem of collaboration on 3D Windows workstations is within the capabilities and scope of The VirtualGL Project.
