One step further would be to embed your entire site in a data: URI.
The biggest limitation would be the resulting length—you'd likely run into character limits when trying to share it on message boards and social media.
Now I remember running across that before. I had forgotten about it. The character limit is a bit troublesome, though, and if you have room to paste a link that long, why not just paste the contents?
