I think your first question explained your need clearly. FUSE is a=20
filesystem layer that lets you filter requests through a user program=20
such as a python script. So, for instance, every time a process opens a=
=20
file, a function is called in your script, and you can look at the name=
=20
of the file being opened, and there decide whether or not to allow the=20
file to be opened. I think this would solve your problem easily. Though=
=20
all the storage is "exported", only files with certain names (ie, *.jpg=
,=20
etc) could be opened. You could also decide which files get enumerated=20
with readdir, etc.
