Has anyone actually done a comparison of the interactive speed of xhost vs ssh
for a graphics-intensive session (say rotating a large protein molecule)? If
you are on a sufficiently private network so the security concerns are minimal
maybe the simplicity/speed of the xhost connection would make the security of
the ssh connection an unwarrented burden.
