I'm a big fan of sideways scrolling in the right places. Apples own product nav on the website would be a great place for two fingered sideways scrolling to be implemented.
It didn't work with swipe gestures as I recall. I remember because I was looking for a good side-scrolling implementation that used swiping about 2 years ago and thought that might have it.
