So if I understand you rightly, the correct procedure for enabling a
local Emacs to project frames on a remote display (after setting the
xhost list) is to establish a ssh tunnel forwarding the X11 port from
the local to the remote computer using something like:

ssh -XL 6000:remoteHost:6000 -l user -N remoteHost

And this will avoid messing around with the DISPLAY environmental
variable on the remote computer?

Am I correct in thinking this /does not/ require an opening in the OSX
firewall for port 6000, since ssh catch the packets before they are
filtered?

Thanks!
