Hier der Javascript Code dafür (benötigt Mootools 1.2)
Code:
<script type="text/javascript">
Page = {
	getSize: function() {
		x = 0, y = 0
		if (self.innerHeight) {
			x = self.innerWidth;
			y = self.innerHeight;
		} else if (document.documentElement && document.documentElement.clientHeight) {
			x = document.documentElement.clientWidth;
			y = document.documentElement.clientHeight;
		} else if (document.body) {
			x = document.body.clientWidth;
			y = document.body.clientHeight;
		}
		return {height: y, width: x};
	}
};
window.addEvent('domready', function() {
	$('menu').setStyles({
		'width': '0px'
	});
	$('frame').setStyles({
		'right': '10px'
	});
	var slidefx = new Fx.Tween($('menu'), { link: 'cancel', duration: 'short' });
	var active = false;
	var slidein = function() {
		slidefx.start('width', 0);
	};
	var slideout = function() {
		slidefx.start('width', 120);
	};
	var mousemovehandler = function(event) {
		if (!event.page) {
			if (active) {
				active = false;
				slidein();
			}
			return;
		}
		var diff = Page.getSize().width - event.page.x;
		if (diff <= parseInt($('menu').getStyle('width')) + 10 && !active) {
			active = true;
			slideout();
		} else if (diff > 120 && active) {
			active = false;
			slidein();
		}
		
	};
	var getwindow = function(iframe) {
		if (iframe.contentDocument && iframe.contentDocument.defaultView) {
			return iframe.contentDocument.defaultView;
		} else {
			return iframe.ownerDocument.parentWindow;
		}
	};
	window.addEvent('mousemove', mousemovehandler);
	(function() {
		try {
			var window = getwindow($('frame').getElement('iframe'));
			if (window.removeEventListener) window.removeEventListener('mousemove', mousemovehandler, true);
			else this.detachEvent('onmousemove', mousemovehandler);
			if (window.addEventListener) window.addEventListener('mousemove', mousemovehandler, true);

		} catch (e) {

	}).periodical(10);
});
