Networking Academic Buildings - Which Infrastructure is Best?

namtro asks: "I'm on a committee at a small private college which is in charge of designing/ordering all networking equipment for a new general science building which is being built. At this point we need to finalize what infrastructure needs to be included to allow us to grow. Should we concentrate on wireless technologies, include fiber to every room, just run CAT5 to every room, put a network port every 4ft in the classrooms, etc? If you were designing a new network for an academic environment, how would spend your money?"
