PEX and GLX were really quite cool, and only recently matched by WebGL. Native 3D apps really could be opened remotely, then download display lists to the local store, and use local 3D rendering hardware. There just wasn't very much PEX interoperability between different manufacturers, because of all the different extensions. Only a rare vanilla app could be remoted in a heterogeneous environment. Some vendors, like E&S, had PEX as the native graphics API. You could not write a purely local app that couldn't be opened remotely, including stereo displays (CrystalEyes) and use of dialbox or spaceball input devices.
