Theoretically, it can be done by granting Machine3 access to VGLServer's root display and manipulating VGL_DISPLAY accordingly. For instance, I sometimes tunnel the 3D commands over SSH for the purposes of testing VirtualGL inside virtual machines that don't have adequate graphics capabilities to act as VGL servers (or you could simply open up TCP access to Machine3's X server and xhost +VGLServer.) However, all of the above is going to perform like a dog.
The problem is that Machine3 has to send the OpenGL/GLX calls to VGLServer using Indirect OpenGL rendering, which means that all of the 3D data (textures, geometry, etc.) are sent over the network, and uncompressed images are read back from VGLServer to Machine3. See the Background article on VirtualGL.org for more info on why indirect OpenGL rendering is bad. VirtualGL is designed to be a direct rendering solution, meaning that the 3D application really needs to run on the same machine as the graphics card. In your case, what I think you really want to do is run a TurboVNC session on Machine3, run VirtualGL on VGLServer, and stream the output of VirtualGL through the TurboVNC session. The User's Guide describes how to do that.
