In addition to what Joshua said, the objects in the URI request path  
are accessible as array members of the global path object:

http://helma.zumbrunn.com/reference/global.html#path

Also, you should be able to access the immediate parent of a hopobject  
using its _parent property, like I'm doing here:

/**
* Provides an array of the path breadcrumbs from
* the this Mocha object up to the root object.
*/
Mocha.prototype.__defineGetter__('path',function() {
    var breadcrumbs = [];
    var obj = this;
    do {
        breadcrumbs.push(obj);
    }
    while (obj = obj._parent);

    return breadcrumbs;
});
