On Lion, a three finger double tap brings up the dictionary. The problem is I have to disable this feature on multiple Macs and cannot be done by clicking on each system. How can this be achieved? Can I use a script? Is there a table with all the multi-touch commands? And maybe I could disable it there?

You can definitely use a script, but I don't know how to disable the commands. – daviesgeek Oct 27 '11 at 20:54

This applescript will turn the option off. Make sure that access for assistive devices is turned on, which is found in Universal access.

tell application "System Preferences"
    set current pane to pane "Trackpad"
    tell application "System Events"
        tell process "System Preferences"
            if window 1's tab group 1's checkbox 3's value is 1 then
                tell window 1's tab group 1's checkbox 3 to click
            end if
        end tell
    end tell
end tell
