when the "live" method is used to bind events with namespaces, all events under the same namespace will be triggered, instead of the specified event.

jQuery("div#id")
 .live("ns.load", function(){alert("ns.load");})
 .live("ns.unload", function(){alert("ns.unload");})
 .live("ns.whatever", function(){alert("ns.whatever");});

jQuery("div#id").trigger("ns.load");

This does not happen using the "bind" method.
