Found this on the VATSIM forums. A guy is updating models for Squawkbox, and has been releasing them as of these past couple weeks. He seems to be working like mad to get them out. More power to him.

The idea is fanastic, however the catch is the models only work if both parties (you and others around you) have the same pack installed. So naturally, word should get out fast to get this update.
