I just hacked this online version of OpenSCAD up (at http://www.pur3.co.uk/OnlineSCAD).
It’s pretty basic right now, but I think it shows promise! You can download STLs from it even as-is! The ability to quickly create and share objects that can be made whatever size you want (think boxes, screws, etc) would be amazing - especially when libraries can easily be created and shared between people.
