I just learned that the UNC Gillings School of Global Public Health actually has public "walkstations" that can be reserved by faculty, staff, and students. The walkstations are treadmills with adjustable-height desks. http://www.sph.unc.edu/weekly_news/august_27_2012_23670_13974.html#new_walkstation I'm not sure which will happen first: treadmills in the library, or desks in the gym.
