Would be better to have a private school, I think. I'd probably go either graduate-only or do something crazy like graduate + coop/internship with $0 tuition, and small. Realistically you have to start small, so I think it's better to be focused. Olin College would be my model for the undergrad program; probably takes a $200-500mm commitment which is about the upper bound of a high net worth endowment. Combine that with a heavily industry-funded graduate program (maybe start focused on a couple specific industries -- say, security and hardware verification, if you could get HP/Intel support), also small and focused. MIT Media Lab would be another model.
