Mapstraction - Mar 2010 - A getDirections function

I was wondering if there are plans to add lets say a getDirections function to
be implemented for each provider.
my thoughts so far, with heavy influence from google, is having an options
object example below

var opt = {
    map: true, //whether to display the polyline on the map
    dirPnl: "divId", //div to hold the textual directions
    dOptions: {
        locale: "", //localisation
        travelMode: "Driving", //weather driving or walking directions
        avoidHighways: true,
        getPolyline: true, //weather the function should return a polyline,
would be true if you wanted to handle the display yourself
        getSteps: true, //if rather than automaticaly sending the step by sted
directions to the div, you would rather handle it yourself
        preserveViewport: true //the map should not be panned after request nad
rendering
    },
    wayPoints: {
        //An array of
        [{ //lat lon pairs
            lat,
            lon
        },
        //or address pairs
        {
            address1,
            address2
        }]
    }
}


//google implementation example
getDirections: function (opt) {
    var map = this.maps[this.api];
    var directions;
    var retObj = {};

    if (opt.map) {
        if (opt.dirPnl !== "") {
            directions = new GDirections(map, opt.dirPnl);
        } else {
            directions = new GDirections(map);
        }
    } else {
        directions = new GDirections();
    }
    if (opt.dOptions.travelMode == "Driving") {
        //set to native
        opt.dOptions.travelMode = "G_TRAVEL_MODE_DRIVING";
    }

    GEvent.addListener(
    directions, ''error'', function () {
        console.log(directions.getStatus().code);
    });
    directions.loadFromWaypoints(opt.wayPoints, opt.dOptions);


    //return an object with the status of the request, driving or walking
distance, the polylines
    if (directions.getStatus().code == 200) {
        retObj.error = false;
        retObj.distance = directions.getDistance().meters;
        if (opt.dOptions.getPolyline) {
            retObj.polyLine = getPolyline();
        }
        return retObj;
    } else {
        retObj.error = true;
        return retObj;
    }
}

This has not been tested, I would like to know whether this would be in
accordance with the standards
expected and if it is something that people would like implemented in
mapstraction.
Any input is appreciated
