You must use a daemon, which we will be using no matter what, as it is
simply impossible to provide the desirable semantics without one. The
daemon can do all the magic of connection sharing, password querying and
caching, file caching, whatever we need.

Adding a FUSE layer to work on top of D-VFS would be quite possible and
something I fully expect to happen.

First, and I've said this more times than I ever cared for, FUSE is NOT
THE ANSWER, and NEVER WILL BE. FUSE is 100% limited to working with
POSIX, and POSIX only, and cannot offer functionality in addition to
POSIX, and that isn't acceptable, because POSIX simply CANNOT do certain
things we want. Simple things like "copy this file" cannot be done with
POSIX - you must instead read/stream the file from the source to the
destination - on a remote share, that means in order to copy a file
(which could otherwise be done 100% on the server-end) you must download
the entire file and then upload it back, just to make a copy. POSIX
isn't up to snuff, FUSE can only offer POSIX, and thus FUSE is not the
answer. It's a great hack to make legacy apps work somewhat well with
modern file system operations, but it is not and never, ever should be
the basis of a modern VFS layer.
I fully support a FUSE module for D-VFS, but I will not see D-VFS get
hamstrung by being designed entirely around FUSE and its limitations.
