You can invoke nautilus remotely in either 'spatial' mode or 'file 
manager mode.'

To invoke in spatial mode, issue the command 'nautilus &' at the 
remote's shell prompt.  The & of course puts it into the background, 
although many GUI programs take liberties with stderr that can be 
annoying.  The & also keeps your remote shell usable for other commands 
as needed.

To invoke 'file manager mode' use 'nautilus --browser &' instead.  To 
see other command line options (there aren't that many) read the man 
page for nautilus.

While your mileage may vary, I find that, if I'm just running one or two 
remote programs, ssh X tunnelling works better than a full remote 
desktop like NX or x2go, especially on really slow WAN links (I do this 
all the time for remote support of CentOS workstations on DSL circuits 
with autossh-maintained reverse tunnels..... a tunnelled X app comes up 
quicker and is usable more rapidly than a full remote desktop is; I can 
have, for instance, system-config-firewall up, running, and changes made 
(but maybe not applied yet) before the initial remote desktop redraw is 
complete with NX, for the most part.  Further, I can move that 
system-config-firewall anywhere on my local X server display with little 
to no redraw lag; try that with NX.  (NX and the others have their 
places; remotely running one or two X clients is not one of them, IMO).

You may also want to look at the ssh documentation and read up on the 
difference between the '-X' command line switch and the '-Y' command 
line switch.
