The draft mentions both options 
(http://tools.ietf.org/html/draft-ietf-oauth-v2-10#section-1.4.3) and 
also states:

"Embedded user-agents often offer a better end-user flow, as they remove 
the need to switch context and open new windows."

Luke Shepard also indicated in his posting 
http://www.ietf.org/mail-archive/web/oauth/current/msg03509.html that 
facebook supports the user agent flow for desktop applications. 
Facebook's iOS SDK seems to use the same technique for mobile apps.

Torsten.
