How much benefit do we really get from ToE? I'm sure that offloading TCP/IP is much simpler than offloading X11, but if ToE helps a huge amount, then offloading X11 will help even more (assuming the relatively slow embedded CPU doesn't become a bottleneck).
I don't see that offloading the X server would be difficult. Isn't it already designed for the client and the server to run at the opposite ends of a communication link? And with a _minimum_ of a 33 MHz 32 bit PCI communication link, we are going to have rather rapid communication between the client and the server.
The only thing that I would need some more info about is how much of an OS is needed to support running the X server. With Linux, I am presuming that you would need the Kernel with not much installed in it. The only things that it will do is communication with the client and swap to disk.
Then there is this DRI stuff but that must also work with the client and server separated.
Swap space is an issue. But I would think that giving it its own swap partition would solve that. The system bus can arbitrate access to the disk. How do you tell Linux not to swap out the X server? Only swap out the screen image data!
