it doesnt inherit style etc. it s also a completely different document for scripting purposes. it s also rather heavy, hard to have 100 iframes in a page

Side note: this would have been a lot easier if in response to, "do you want that snippet not to be sandboxed?" you'd just said, "yes".

What you're proposing stands little chance of being implemented, given the security implications.

it s just an idea not a proposal. it would be sandboxed, the idea is to allow html only, so as to avoid scripting. don't we do that all the time with ajax?
