Is there a way to get a user's achievements list from Xbox without dealing with screen scraping etc.? How do sites like http://www.trueachievements.com do it? (they're definitely not screen scraping as they do not have my Live ID credentials...)
I know there's the Xbox LIVE Community Developer Program (XCDP) that provides some API but they do not provide achievements information as far as I can tell (links below)
