I came up with some js which can prevent framebusting. A side effect of it is the page trying to bust will stop loading. Meaning if the framebusting code is at the top of the page you will effectively be left with an empty frame, but the frame bust _will_ fail. If the framebusting code is at the footer of the page then you will get a fully loaded page which failed to framebust.

code here:
