With AIGLX, OpenGL can now be pumped over a remote X session.  
Colorspace conversion and scaling would be done server side (on the 
client), so you would be sending raw YUV video.  That's 630Mbps for 
720p60 and 710Mbps for 1080i60.  Not trivial, but certainly in the realm 
of possible.  Being able to send one HD video stream per network link 
would not be very practical.

VDPAU and the like are all direct rendering, meaning they cannot be 
proxied through X over the network.
