How do we make sure it works across different platforms? I don't think we should be encouraging authors to create website that only works with applications on a particular platform.

If we are to allow arbitrary data types, then I would really like to provide an abstraction around it so that the Web authors don't have to detect platform and do different things for each platform. And if that's unpractical or impossible, then we shouldn't allow arbitrary data types. - Ryosuke
