It's a strange border case, and it is hard to define exactly what the
program is. I am not sure you are familiar with how applications in
Mac OS X and the iPhone OS work, but what appears like an application
to a user is actually a directory containing the executable file and
various resources. In the case of the iPhone application I am talking
about, the proprietary images will have to be part of the application
bundle, but they will not be contained in the executable file itself.
I suppose I should at least require that the source code builds
correctly and gives a fully usable application (albeit perhaps with
slightly less nice-looking graphics) without the proprieatary images.

No, I don't want to modify my license. I definitely want programs
derived from mine to use the GPL.
