        <!--    Input module.

            This example uses the 'oss' module. It takes input from the
            OSS audio device (e.g. line-in), and processes it for live
            encoding.  -->

        <!--    Stream instance.

            You may have one or more instances here.  This allows you to
            send the same input data to one or more servers (or to different
            mountpoints on the same server). Each of them can have different
            parameters. This is primarily useful for a) relaying to multiple
            independent servers, and b) encoding/reencoding to multiple
            bitrates.

            If one instance fails (for example, the associated server goes
            down, etc), the others will continue to function correctly.
            This example defines a single instance doing live encoding at
            low bitrate.  -->

        <instance>
            <!--    Server details.

                You define hostname and port for the server here, along
                with the source password and mountpoint.  -->
            <hostname>a.stream.mayfirst.org</hostname>
            <port>8000</port>

                and samplerate given in the parameters to the oss input
                module above or the remsaple/downmix section below.  -->
            <encode>  
                <quality>0</quality>
                <samplerate>22050</samplerate>
                <channels>1</channels>
            </encode>
            <!-- stereo->mono downmixing, enabled by setting this to 1 -->
            <downmix>1</downmix>
            <!-- resampling.
                Set to the frequency (in Hz) you wish to resample to, -->
            <resample>
                <in-rate>44100</in-rate>
                <out-rate>44100</out-rate>
            </resample>
        </instance>

Stick the above in a file named something like "mystream.xml" and run Ices2 with it as follows:
