Not only is it possible, I'm confirming it to be the case; I have my PS3 slim connected to my Panasonic V10 and when I hit viera link it turns on the PS3, I can navigate the XMB, I can use the blu-ray color buttons, the play, pause, stop, forward, and reverse buttons all work. There are also buttons to replicate other PS3 buttons like: sqaure, triangle, circle, and X. The only real PITA is that the chapter skip buttons on my V10 remote seem to be ineffective, I have to pull up the disc menu or the PS3 menu via the triangle button. Also, there is no select button (to display time and codec).
Overall, it's not bad; if they included support for the select button and next and previous chapter I would consider sticking with this and using the PS3 controller to surf the web (which I do anyway in my other HT room where I have a harmony BT to IR converter). As it stands, I will probably end up buying another BT to IR converter but with the CEC functionality perhaps I won't rush to do so.
