I am running v1.3.2 and it does not seem like there are any events dispatched when shipment is created. Your best bet is to override the default adminhtml shipment controller and add an event dispatch with an event name of your choice. You can handle this event with an event observer in your module.

If your client is using the API to ship orders, you should also take care of raising an event in the api code responsible for creating shipments.
