Keep in mind that wp_footer doesn't necessarily need to be called from
footer.php so checking there isn't terribly reliable.

This idea intrigued me so I wrote a small proof of concept plugin to
test this.  If you are interested check it out here:

Perhaps not the best or cleanest way, but off the top of my head I
couldn't think of a better way to do it.
