WMRMRights.AllowCollaborativePlay
The AllowCollaborativePlay property specifies and retrieves a Boolean value that indicates whether the license permits consumers to play protected content in a collaborative peer-to-peer session.
Syntax
Boolean = .AllowCollaborativePlay .AllowCollaborativePlay = Boolean
Parameters
This property takes no parameters.
Return Values
If the property succeeds, it returns a Boolean value indicating whether the content can be played in a shared session. If it fails, it returns E_FAIL.
Remarks
The default value of this property is False.
Collaborative play allows consumers who use peer-to-peer services to play protected content. For example, users of MSN Messenger 2004 can play protected content in a MusicMix session.
Up to 10 users who know each other and are connected through the Internet can join a group, sometimes called a party, that has a single shared playlist of music tracks. All concurrently connected users can be contributors by providing additional music tracks (DRM-protected or not) from their computers to the shared playlist. Each new track is then preemptively and securely distributed to all other connected party members, called listeners. The new track is securely cached on each listener's disk until it becomes the active track in the shared playlist. Then all concurrently connected users listen to the same track at the same time according to the order of the shared playlist.
The audio contained in licensed content must be downgraded by transcoding to 64 Kbps before it is cached in persistent storage or transmitted over a public network. This restriction does not apply to video.
No more than 10 listeners can have a copy of the content keys at one time.
