I don't know about Hans, but I was thinking of something like this (I made this in angular, but it could be ported): http://plnkr.co/edit/5oCqEdZvWQ7tWX0OBrq4
Touch-friendly, flick-enabled, scrollbars in both/either direction, easily skinned via css.
Chrome allows you to skin scrollbars, but I think it's the only browser that allows it. This would unify the experience across browsers and allow you to style scrollbars to match the themes on your site.
Any chance one of you voters could provide more detail about these scrollbars that are being requested? =)
