http://www.versiontracker.com/dyn/moreinfo/macosx/20854 This came up in my RSS feed from versiontracker. Any thoughts? It's a kernel extension that replaces the current drivers in the iBook and PowerBook G4. It enables vertical scrolling, horizontal scrolling, mapping the hardware button to left- and right-click (!!!) and mapping the trackpad to left- and right-click. It's a beta, however. Any thoughts on this product? Edit: from the same folks that brought you MenuMeters!
