There's also LUFS (which incidentally supports gnome-vfs modules like fuse supports kioslaves - can't have one doing both, it seems ;). I'd really like to see one of these make it to the default kernel...

Anyway, anyone know if the fuse kernel interface is secure nowadays, in a sense that one can safely allow users to freely use even their own filesystem code to mount things? I asked basically the same on the lufs list a good while back, and there were, in effect, no answers, and the lufs daemons seem to run as root which is a kind of telltale sign that one doesn't want arbitrary user code there...

Security is one of the main design principles of FUSE. The only operation that requires root access is the mounting, and that can be done fairly securely by a non-root user with the help of a suid program (fusermount).
