I have been using sshfs (mounting SFTP servers) with MacFUSE on my Mac Mini (Snow Leopard). When I mount an SSH server, I can do it without having to be root, and i'm fine. My friend, on the other hand, tries to mount my SSH server, and it says access denied. He then runs the mount as root and it works fine. The issue with running as root though, makes it not accessible by Finder. He's an administrator on his computer (which is Snow Leopard on a MacBook (White)).
