For virtualization of things like the DOM, reusing the host's [[Class]], or being able to fix a proxy into a host object (if I correctly understand that those are what is being discussed), is not actually what is wanted. Rather, it needs to be possible to create a *separate* set of objects which have the same relationships among *themselves*. That is, given that in browsers document.[[Class]] == HTMLDocument, we want to be able to define MyHTMLDocument such that myDocument.[[Class]] == MyHTMLDocument.
