[fuse-devel] POSIX completeness of FUSE?

I have questions about the POSIX completeness of FUSE.  Earlier there
was talk of a "filter" operation in 2.7 which would allow file systems
to access their underlying contents; if I were to mount a generic FUSE
file system overtop, say, /, what would be the consequences?

The interesting thoughts I have here are that transparent encryption and
compression file systems could be used globally, such that you would
"mark" files to be encrypted or compressed and it would be done on a
per-file basis.  However, if you mounted everything like this, you would
encounter problems if FUSE didn't support, say, shared file mappings.

In the future I want to toy with a user space access control system
using FUSE, which is primarily why I'm worried about this.
