I think this would be very useful and can prevent conflict between plugins. Example of how it could work:

var $el = $('#my-element');

$el.on('click', function () {...});

$el.on('mySlide.next', function () {...});
$el.on('mySlide.prev', function () {...});

$el.off('mySlide'); //unbinds all events within this namespace (next and prev)

All the best.
