So basically if I write a program that works in both Gnome and KDE
I should (according to your description) implement my own VFS that
will use the Gnome or KDE VFS that will then use the OS VFS.

Is it only me finding that a little silly?

I mean, if I am to have the same functionality under neither Gnome
nor VFS and they don't support something I need I _NEED_ a vfs so
that my program is so totally independent on anything at all.

My program calling My VFS which calls KDE/Gnome's VFS which calls the OS
VFS will be slowe than just calling the VFS immidiately - I do hope you
can see that.
