RIM is making a big show at the Game Developers Conference that they are sponsoring this year. SemiAccurate (via CB) caught a demo at the show of an app a RIM employee developed that allows him to control his PlayBook game from what looks like a BlackBerry Torch 9850 smartphone. The concept is very cool though it has been done on other platforms in a limited form. Either way I think it could be really cool if RIM extended BlackBerry Remote or gave developers an API to do it themselves and create slick integrations like this.
Hopefully we will be seeing this app actually released beyond just a proof of concept!
