You could just use a tile layer that always returns a blank image. Something
like this should work :
var vzl = new OpenLayers.Layer.TMS(
'test', 'http://google.com',
{
getURL : function(bounds){ return "
http://yourserver.com/blank.gif";; },
buffer : 0,
isBaseLayer : true,
numZoomLevels : 22,
transitionEffect: 'resize'
}
);
map.addLayers([vzl]);
Not sure if this falls into your hack category, but it's simply re-using an
existing layer type, so you don't have to create a new one.
