this plugin allow you to filter text pasted into iframe (tested on latest Firefox and Chrome and Internet 8) it will not work in Opera

$(function() {
	$('iframe').designMode(true).filterPaste(function(text) {
		return text.replace(/<\/?\w+[^>]*>/gi, "");
	});
});

this will strip all tags from pasting text (like when you copy from a web page)

1. document
2. body
3. designMode
4. selection
5. range
