I've played around with multitouch on Ubuntu, it does work with some hardware (but not if the driver intercepts the touches and synthesizes something like scrollwheel events, that's bad).

See eg. https://wiki.ubuntu.com/Multitouch and https://lists.launchpad.net/multi-touch-dev/msg00997.html

I have full multitouch on this laptop, and use the two-finger scrolling and triple click that is provided by the synaptic driver everyday. The inability for programs to directly use gestures isn't great though.
