I have tried to get 2 of my professors to use AW in their programs without any luck.
One was just too involved in SL to be convinced of a look. The other saw AWGATE and then balked. She thought the world was prettyish(no bells or whistles), but empty, and she had little idea of what to do. She never gave me the opportunity to show her, she went in on her own. She's a Computer Science teacher, and this convinces me that AWGATE is the wrong place to send people. There absolutely needs to be a tutorial world(or built in tutorial), similar to how SL does it, that teaches someone to use the interface and evinces the positives and activities of the program.
