Hey, a friend of me is trying to use the <noframes> tags to dump keywords (since almost every visitors has frasmes enabled, noone would see the noframes section except googlebots), but exactly how dangerous is this for your website? I am pretty sure that google will find out, since it is against their policy of showing different content to visitors and googlebots. Is the method known and detected by googlebots? For the record; I'm not planning to use the method, since I think it will get back on you someday.
