fwiw, googlebot has been capable of this for many years, and has been doing it for... a while. I'm not sure how long, because I stopped using JavaScript for cloaking around 2006. At PubCon Boston, The Honorable Mister Cutts confirmed this saying they "could" do it, but they "presently did not".

The bot executes inline JavaScript, and it will execute "onclick" events on clickable elements, like <a>. But AFAIK it still won't submit a <form>, and it doesn't trigger onmouseover, onfocus, onblur, etc. Correct me if I'm wrong.
