i believe he's referring to being able to create an FBM channel with a pose file, like this bit for example:

{
    //based on HeelHelper.pz2 by Les Bentley
    //this file only works in P6 and above
    version
    {
        number 6
    }
    createFullBodyMorph Eyes Up-Down
    createFullBodyMorph Eyes Side-Side
    createFullBodyMorph Eyes Crossed
    actor BODY
    {
        channels
        {
            valueParm Eyes Up-Down
            {
            name Eyes Up-Down
            initValue 0
            hidden 0........etc

lost in the wilderness
