sshfs is a fuse filesystem implementation over SSH.
All you need is the "Subsystem sftp" line on the receiving end
/etc/ssh/sshd_config (which most everyone has) and to load the sshfs kernel
modules (apt-get install sshfs in *Debian)
Then you (need no root privileges):
sshfs user@remote_system:/path/to/mount /my/local/path
And you are done... :)
You umount it with
fusermount -u /my/local/path
It is almost always true that "if you can SSH into, you can mount".
If you need to access the mount as "root" you need to do some simple sorcery
(as you would need on NFS too), but for the most part, it is brain dead.
YMMV...

PS: If you have any question you will get any answer... :)
