There are many ways to sandbox Javascript, both serverside and browser-side.
Are there any ways to "sandbox" DOM access? I.e. give untrusted 3rd parties access to a DOM element in a predefined spot? AFAIK the only tech that allows for this is iframes, which are unfortunately heavy and slow. I'm writing an app that can host plugins, and unfortunately, I think giving plugins DOM access means they can now literally do literally _anything_.
