[Zope] Zope start finished

Hello list, we have a local Zope installation on a laptop to present our product. Our problem is, that starting Zope lasts a relative long time and we have no feedback when our product is ready to work. Is there a possiblity to show the user e.g. a message box when zope and the product are ready to work and the user can start the presentation? For example is there a method that can be overwritten in order to do that? Many thanks in advance, Ulla.
