Well, as discussed in various places before, FUSE is pretty useless,
because it (a) works at the wrong level and (b) is limited to Linux 2.4
Doing remote file system abstraction in the kernels VFS layer is exactly
the wrong abstraction level, as that limits you to the POSIX API, which
is certainly not what you want in 99% of all (desktop use) cases, esp.
not within a smart file manager. E.g. there's no way for backends to
pass additional information (like the suggested mime type, metadata,
capabilities, etc.) to the application; you are limited to the plain
POSIX API. And even worse, the POSIX API imposes requirements on the
backend that require awful hacks to make it work with some remote
