As hard-drive capacities continue to explode, a versioned desktop
filesystem is very much a desirable feature for users - that's why
applications like Word have their own self-rolled versioning systems,
just as many apps have had to roll their own meta-data databases.

So, don't rule it out as a server only feature - it could make D-VFS
'forward looking' :)
