sshfs has the advantage over a KIOslave or GnomeVFS that any program can use it. For instance, in Kubuntu Amarok wasn't able to play my remote music through fish:/ but worked fine using sshfs.
1) Install the software
sudo apt-get install sshfs
2) Add fuse to /etc/modules
sudo nano /etc/modules
3) Add yourself to the 'fuse' group, then log out and log in again.
sudo adduser your-username fuse
4) Create a mountpoint and give yourself ownership
sudo mkdir /media/mount-name
sudo chown your-username /media/mount-name
5) Mount the filesystem
sshfs remote-system-name:/remote-folder /media/mount-name
6) Unmount the filesystem
fusermount -u /media/mount-name

I've run into a strange problem on two Kubuntu machines where, after using sshfs, you're unable to unlock your own computer. Logging in works fine, but you can't return from a password-protected screensaver. My solution was to start a new session, change my password, then return to the old session and use the new password to unlock it.
