Using new BlazeDS streaming channels in CF 9.0.1

The New Features document for ColdFusion 9.0.1 lists support for two new streaming channels in the included BlazeDS:

my-streaming-amf               coldfusion.flash.messaging.CFStreamingAMFEndPoint
secure-streaming-amf          coldfusion.flash.messaging.SecureCFStreamingAMFEndPoint

I tried hacking together a stanza for the CFStreamingAMFEndpoint in my services-config.xml mirroring some of the existing CF channels and the streaming-amf channel config from the main BlazeDS distro, but I haven't hit upon a configuration that works. Does anyone have a working example of using this channel from ColdFusion?

Here's what I cobbled together:

        <channel-definition id="my-streaming-amf" class="mx.messaging.channels.StreamingAMFChannel">
            <endpoint uri="http://{server.name}:{server.port}{context.root}/flex2gateway/cfstreamingamf"
                class="coldfusion.flash.messaging.CFStreamingAMFEndPoint"/>
            <properties>
                <connect-timeout-seconds>5</connect-timeout-seconds>
                <coldfusion>
                    <!-- define the resolution rules and access level of the cfc being invoked -->
                    <access>
                        <!-- Use the ColdFusion mappings to find CFCs-->
                        <use-mappings>true</use-mappings>
                        <!-- allow "public and remote" or just "remote" methods to be invoked -->
                        <method-access-level>remote</method-access-level>
                    </access>

                    <!-- Whether the Value Object CFC has getters and setters. Set the value of use-accessors to true if there are getters and setters in the Value Object CFC. -->
                    <use-accessors>true</use-accessors>
                    <!--Set the value of use-structs to true if you don't require any translation of ActionScript to CFCs. The assembler can still return structures to Flex, even if the value is false. The default value is false.-->
                    <use-structs>false</use-structs>

                    <!--Set the value of serialize-arrays-to-arraycollection to true if you require ColdFusion arrays to be converted to ArrayCollection on the ActionScript side. The default value is false. A false value
                    will convert ColdFusion Array to ActionScript Array-->
                    <serialize-array-to-arraycollection>false
                    </serialize-array-to-arraycollection>

                    <property-case>
                        <!-- cfc property names -->
                        <force-cfc-lowercase>false</force-cfc-lowercase>
                        <!-- Query column names -->
                        <force-query-lowercase>false</force-query-lowercase>
                        <!-- struct keys -->
                        <force-struct-lowercase>false</force-struct-lowercase>
                    </property-case>
                </coldfusion>
            </properties>
        </channel-definition>
