Petr, to a certain extent, yes, VirtualGL is doing that.
However, VirtualGL is using VNC as the transport medium but I'd like to have a tighter integration with the Xorg architecture, otherwise Windows are bound the the VNC client space. Moreover, compression/decompression is handled by the CPU and I'd have this handled by the GPU (application and client side). But it's a good start and I've already contacted those folks. In order to get all this closer into Xorg, here's what I have in mind: for rendering I'd like to use a TESLA board with an render pipeline written OpenCL or CUDA. Within a post-processing step the frame buffer (which is actually an off-screen buffer in OpenCL's global space) is compressed and picked-up by a GLX driver in user space. From what I read, AIGLX has the means transferring pixmap images directly to an GLX extension (GLX_pixmaptotexture or something) within the graphics driver. I'd use AIGLX to pass the image directly through to the (DRI) driver an let a pixel shader decompress the image. This way it goes effectively to the frame buffer of the clients X-server. Since AIGLX is a Fedora project, I hope that anyone here is able to provide me with further technical information about the protocol and the architecture - haven't found anything so far. As mentioned, whatever comes out of this I'll gladly contribute to the project.
