This is rather nice. I'm not sure I see a use case for it, but it's fun to play with nonetheless.
One tweak I'd make.. have a static box attached to one corner that doesn't zoom with the rest of the page for a user defined message, eg "F2 to reset". If you've zoomed out a long way it's very easy to get lost, so a reminder of how to get back to the content is critical. Alternatively, limit the zoom so the user always has some portion of the content visible.
