groupspec strings
that can be passed to NetStream and NetGroup constructors.
A groupspec specifies an RTMFP Peer-to-Peer Group, including
the capabilities, restrictions, and authorizations of the member using the groupspec.
By default, all capabilities are disabled, and peer-to-peer connections are allowed.

ipMulticastMemberUpdatesEnabled | property |
ipMulticastMemberUpdatesEnabled:Boolean| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10.1, AIR 2 |
Specifies whether information about group membership can be exchanged on IP multicast sockets. IP multicast servers may send group membership updates to help bootstrap P2P meshes or heal partitions. Peers may send membership updates on the LAN to help bootstrap LAN P2P meshes and to inform on-LAN neighbors in global meshes that other on-LAN neighbors exist. These updates can improve P2P performance.

maxSupportedGroupspecVersion | property |
maxSupportedGroupspecVersion:int [read-only] | Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 11.5, AIR 3 |
Specifies the maximum groupspec version supported by
this runtime. A groupspec having a version greater than this
will fail in this runtime.

minGroupspecVersion | property |
minGroupspecVersion:int| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 11.5, AIR 3 |
Specifies the minimum version number the generated groupspec
will have. The groupspec version number may be higher than this
value if an option requiring a higher version number is enabled. A
groupspec having a version number lower than the minimum
supported will fail.

multicastEnabled | property |
multicastEnabled:Boolean| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10.1, AIR 2 |
Specifies whether streaming is enabled for the NetGroup. Methods used for streaming
are NetStream.publish(), NetStream.play(), and NetStream.play2().
By default, this property is FALSE (streaming is disabled).

objectReplicationEnabled | property |
objectReplicationEnabled:Boolean| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10.1, AIR 2 |
Specifies whether object replication is enabled for the NetGroup. By default, this property is FALSE (object replication is disabled).
Implementation

peerToPeerDisabled | property |
peerToPeerDisabled:Boolean| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10.1, AIR 2 |
Specifies whether peer-to-peer connections are disabled for the NetGroup or NetStream. By default, this property is FALSE (P2P connections are enabled).
If P2P connections are disabled (you set this property to TRUE), the P2P warning dialog is suppressed. In this situation, no neighbor connections can be made, and no group members use upstream bandwidth. Disabling P2P connections in this way is generally useful only when receiving multicast streams via pure IP multicast.

postingEnabled:Boolean| Language Version: | ActionScript 3.0 |

serverChannelEnabled | property |
serverChannelEnabled:Boolean| Language Version: | ActionScript 3.0 |
| Runtime Versions: | Flash Player 10.1, AIR 2 |
Specifies whether members of the NetGroup can open a channel to the server. By default, this property is FALSE.
A channel to the server must be opened before the server can provide supporting functions to group members. Depending on server configuration, supporting functions may or may not be provided over this channel.
