This is SOO 6 months ago. Well not really... But still. The program I think is most useful that utilizes the SMS is iAlertU, a security program that triggers an alarm when the macbook(pro) is moved or played with. Pretty cool app. It it armed using the Front Row remote, and it sounds like a car alarm. http://www.slappingturtle.com/home/
I think I damaged my Superdrive in my MacBook this why -- I had to send it in for a replacement. If you are doing this with Virtuedesktops, be very careful where you smack.
