MyAppleGuide reports that Apple might have customizable 4-finger gestures planned for the upcoming Snow Leopard release. The interface discovered by MyAppleGuide would allow users of multi-touch capable Macs to define their own gestures.
The unibody MacBooks and MacBook Pros had 2, 4-finger gestures for the new trackpads of OS X Leopard at the time of its release. Chris at MyAppleGuide has accidentally come across a hidden preference pane, an unused .nib file that allows the customization of 4-finger gestures on the new glass trackpads included with Apples latest notebooks while trying to reverse the 2 currently available gestures.

Currently, the preferences pane has drop down menus for each direction of swipe
- Swipe up - Shows the Desktop
- Swipe down - Triggers Expose
- Swipe horizontal - Brings up the Application Switcher
The above preferences cannot be customized. However, the unused interface would allow functions like switching between Spaces and opening Dashboard

The hidden .nib file can be found at /System/Library/PreferencePanes/Trackpad.prefPane/Contents/Resources/English.lproj/FourFingerSwipeGesture.nib on Mac OS X Leopard versions of multi-touch capable Macs.
