When you open a network share in Nautilus, an entry for that folder is created
in ".gvfs", off of your home directory. (Gvfs must stand for Gnome Virtual File
System.)

So: If I use Nautilus to open the shared folder "rs-harpo" on my "StrayCat"
machine, the command line reference for that folder is:

"~/.gvfs/rs-harpo on straycat"
