If this is an on-line product (for example, form-based), have you considered putting the developer information in the error page you return if values are not filled in or filled in incorrectly? Also, if it is form-based, you might also have a particular "open sessame" value in one or more of the form elements that is unlikely to be put there that opens the about page.

Just a few thoughs from an egg. Some of the thoughts above seem quite good, though.
