MaximumPacketSize	Specifies and retrieves the maximum packet size that can be sent by the unicast data sink.
MinClientPacketSize	Specifies and retrieves the minimum value of the packet size that a client can request.
OptimalPacketSize	Specifies and retrieves the optimal packet size sent by the unicast data sink.
TCPEnabled	Specifies and retrieves a Boolean value indicating whether the unicast data sink can use TCP when selecting a streaming protocol.

    Dim Plugin As IWMSPlugin
    Dim AdminUnicastSink As IWMSAdminUnicastSink

Try
    ' Create the WMSServer object.
    Server = New WMSServer()

    ' Retrieve the plug-in to be configured.
    Plugin = Server.UnicastDataSinks.Item("WMS Unicast Data Writer")

    ' Retrieve the custom interface of the plug-in.
    AdminUnicastSink = Plugin.CustomInterface
