Remote Desktop passes draw calls from server to client instead of screen-capping and sending bitmaps. Similar to remote X11.

Ah. May make a lot of difference - or would it also partly depend on whether the data (e.g. args sent with the calls) was raster or vector? Think I read recently that some versions of OpenGL do the same or similar. Not an expert here, but interested in the concepts and techniques.

And yet the boys over at xorg wants to throw that part of X11 out the window and use screen scraping instead...
