There doesn't appear to be a general solution to "natural scroll". There's the .XModmap hack that you can find using Google (which I've implemented), but it turns out that it doesn't work consistently across applications. Most notably, GTK 3.4 (with "smooth scrolling") uses a different input method. It is possible to switch the mapping for synaptics touchpads, but I cannot find out how to get perfectly uniform behaviour across the board. I need to know how elementary wants to handle this. Just support touchpads? Don't support NS at all? Unfortunately, I think the safest option would be not to support it at all: see https://bugzilla.gnome.org/show_bug.cgi?id=674716, comment #2 --vincentnys

As for multitouch, touchegg seems like a valid option. My own touchpad seems too inaccurate to test this, though. Can someone else implement and test this part? --vincentnys

GNOME's mock-up looks cleaner. DanRabbit's mockup-up looks cluttered. --swizzle
