Things are coming together for the PlayBook moon project right now - the rover is currently being assembled at McMaster, and our team of video game programmers @ triOS College are creating the software that will run on the rover and control it remotely.
The main computer on the rover will be an OMAP 4430 Panda board (basically the exact same hardware in the PlayBook), and by the end of the summer we plan on having a rover that we'll drive around on the ground using a custom Wi-Fi connection between a navigation app I created on my BlackBerry and the Panda board. Any BBM messages sent to my BlackBerry will be routed to the Panda board, where it will reply with its coordinates and a cheeky artificial intelligence response (depends on the message you send). For fun, we plan on including a Space Invaders routine that, when invoked, moves the rover side to side with shooting sound effects ;-)
