> While it's a cute idea, I doubt this feature of X has serious support behind, and I don't think any future graphics system, be it Wayland or something else, will support it. Sending rendering commands over a network is just much worse for the vast majority of applications than rendering on the source system and sending a (compressed) video stream.

I totally disagree. Obviously it just depends on your use case, but most user interfaces are almost completely static and sending vector commands is going to be a win over raster in almost any condition. Low bandwidth? Vector wins. High RTT link? Vector wins. Dual 4k screen? Not a problem with vector, but difficult with video and disastrous with raster.

One may argue whether the current implementation in Xorg is useful or not, but conceptually, I see vector as definitely the way to go. Vector even allows you to do some predictive interpolation, while raster -- good luck.

Maybe sending HTML+javascript over the wire is the solution, ala Display PostScript except more fashionable these days. Thinking about it, one could argue that's exactly what we have these days with the web...
