No messing with the clipboards - can be done up nicer, much nicer, to have like the redirect message that is loading in the iframe show a saving message (though it should happen fast enough that most wont see it) etc.

If the user 404s - then they will never redirect to the showthread page, which means they will never get the framebuster - and they will still be sitting with their post in front of them - most probably would not even notice they 404ed just hit submit again, and watch it go through, never even thinking twice about it or realizing that normally they would be cussing right about then
