Colleges sell naming rights to bathrooms | Inside Higher Ed

So a few institutions of higher education, including my very own University of Colorado at Boulder, have sold the naming rights to a bathroom. Is selling the naming rights to any part of an educational institution okay? If so, which parts? Where do we draw a line between keeping tuition lower and embarrassing the institution?
