From what I read, WP7 should be Live ID centric (apparently you need one even just to activate the phone). What surprised me is that the API don't allow any kind of access to those credentials, so I guess that even a registered Live ID application may have to provide its own login page and manage the authentication.

 

Assuming this is true, I wonder if it's just a feature cut dictated by the looming deadlines, or if there is some deeper reason (security? privacy?) that I cannot grasp. For sure it is going to make using Live ID less appealing...
