Romeo - Bluetooth Phone accessory

I've been looking for a little app to to improve communication between my blue tooth cell phone and my powerbook for a while. Romeo looks like it fits the bill. It has a variety of ways to use your cell phone as a remote control. What I like is it can turn on my screen saver when I walk away from my power book, and it will tell me who's calling when my phone rings. I might use the phone to page through presentations as well, so i don't have to stand next to my lap top while I talk. Simple stuff - but it's taken me a while find an app that's free (as in beer) and does it well.
