Anyone know where or how to obtain a database of worldwide beaches?

Required fields are:

You can go the administrative way by taking the capital coordinates or go the geometrical way by calculating country's centroid.

In any of these cases, Geonames database could help you.

Update : You can also use the Creative Commons dataset format world borders shapefile in which any countriy has a lat/long coordinates associated.

I don't know how it is computed. Using that shapefile you will also be able to compute centroids if needed.

[GIS] How to find direction points using Google Maps API 3

When taking a look at this reference DirectionsRenderer Reference, look for the event

directions_changed

After rendering your directions, introduce an event listener on the DirectionsRenderer object. Something like this:

var directionsDisplay = new google.maps.DirectionsRenderer({draggable: true});
var directionsService = new google.maps.DirectionsService();

var mapOptions = {
 zoom: 7,
 mapTypeId: google.maps.MapTypeId.ROADMAP,
 center: australia
};

var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);

directionsDisplay.setMap(map);
directionsDisplay.setPanel(document.getElementById('directionsPanel'));

google.maps.event.addListener(directionsDisplay, "directions_changed", function(){
    //do what you wanna do here i.e. get the modified path of the direction
});

Very important thing is to make sure you set the draggable attribute of the DirectionsRenderer object to true. Note that the code here is mainly take out from the link Mapperz gave in his comment.
