A while ago I started thinking about how multi-touch and gesture support could look like. Looking around on the web and in the research literature, I found that all the multitouch systems are a hack (I'm talking about software integration here, not the hardware!). Multi-touch support needs to be in the windowing system. Any client-side approach is wrong. (Feel free to disagree with me on that). We don't need gesture support in X. Gestures depend a lot on the context. What we really need is a way to convey events from a touch device to a client application.
