If you're using the ALSA library, you can use the following definitions
in /etc/asound.conf or ~/.asoundrc to get two independent virtual
devices:

pcm.left {
        type plug
        slave.pcm {
                type dshare
                ipc_key 12345
                slave.pcm "hw:0,0"
                slave.channels 2
                bindings {
                        0 0
                }
        }
}

pcm.right {
        type plug
        slave.pcm {
                type dshare
                ipc_key 12345
                slave.pcm "hw:0,0"
                slave.channels 2
                bindings {
                        0 1
                }
        }
}
