Checking arXiv.org, I notice that SeeSat participant Jonathan McDowell has produced a paper reexamining the "edge of space" question:

The Edge of Space:  Revisiting the Karman Line
Jonathan C. McDowell
Harvard-Smithsonian Center for Astrophysics, 60 Garden St, Cambridge, MA 02138, USA

Abstract

In this paper I revisit proposed definitions of the boundary between the Earth’s atmosphere and outer space, considering orbital and suborbital trajectories used by space vehicles.  In particular, I investigate the inner edge of outer space from historical, physical and technological viewpoints and propose 80 kilometers
as a more appropriate boundary than the currently popular 100 km Von Karman line.
