Definitely could be, but they must have gone through the trouble of setting up a larger number of little nodes if that's the case, as a lot of the largest exit nodes on the network have known operators. For example, as of a few weeks ago, a friend/grad students put up a top 5 (by bandwidth) in the US in the Media Lab at MIT, and a different friend ran a top 10 out of an MIT dorm room a few years ago before eventually getting shut down by admins. Fortunately, this one will likely stay up as it's under Joi Ito's purview now.
