Is it bullet proof, i.e., work around(s) the site using the iframe can use to bust the framebuster.?

No, it's not 100% bulletproof - but a workaround would be extremely complex and take a level of expertise that is way beyond 99.9% of webmasters.

I used to think framebusting was bulletproof, but then for a short period of time a few years back, Yahoo Image Search was actually breaking framebuster scripts. I complained about it as did others, and the frame-breaker breaker script was removed. It was apparently created by an overly energetic engineer who pushed the script live without the knowledge of top managament.
