I like one Wayland idea someone had. He pointed out that with the latest Intel chips you can do a realtime video encode of each composited window and ship that over the network using less bandwidth than most of the current VNC solutions.

Yeah... but video encoding is lossy and intended for animated real-world scenes. Have you ever seen what a window containing lots of text (or even line drawings) looks like after a video encoding pass? Ugly and unreadable, that's what.

(This is not an indictment of video codecs: they are largely very good at what they do. But what they are designed to do is encode animated real-world scenes, not flat window images.)

If you did not move the text around, I believe that after several frames it would be clear and readable as each frame increased the resolution.

I have watched shows that had quite a bit of text in them. Some sports shows have a bunch of statistics and on HDTV they are pretty crisp.
