I'm not very familiar with Steam in-home streaming, but my guess, based on the advertising materials for it, is that it's an application-specific screen scraping solution. In other words, a copy of Steam runs on one PC and sends a copy of the graphics it's rendering on that PC's physical display to another copy of Steam running on another PC. I don't know the technical details of how they do that, but it is almost certainly a single-user solution. VirtualGL, on the other hand, is designed to be a multi-user solution, and it is not application-specific. With TurboVNC or another X proxy, you can create multiple virtual desktop instances on a single Linux/Unix machine. Then you use VirtualGL to launch any 3D application in that virtual desktop session. VirtualGL modifies the GLX and OpenGL commands from any arbitrary application such that 3D rendering is redirected into off-screen buffers on the GPU, thus allowing multiple applications and multiple users to share the same GPU, and thus allowing OpenGL applications to run with 3D hardware acceleration in the X proxy session (which ordinarily wouldn't be possible-- virtual desktops normally can only support software OpenGL.)
