Other examples would be web browsing and Flash video. Now the web supports alternative style sheets to present a simpler layout on mobile devices and Flash supports a supports a video format which takes less work to decode - YouTube offers it as an option. Perhaps the Java TightVNC client declines the trickier encodings, exactly as I have to pass options to the C client to do. By default the C TightVNC and RealVNC clients assume "we can has cycles," which leaves me wondering quite what situations have sufficient computing power with such measly bandwidth as to make the 'heavy' encodings worthwhile. Sorry for the late reply, had to ignore email to get other things in order. -- freedesktop.org, because unix doesn't make things harder enough. Ethan Grammatikidis eekee57@fastmail.fm
