I agree.
Although it may be a filesystem by definition - a filesystem for NT/ROS should operate solely in kernel mode ... and work there completely (i.e. all other kernel components must be able to use it). Which implies usually that you could potentially boot from it or mount it before usermode processes are alive.
Anyway I would also be interested in it and especially a pointer to more details about it.

It sounds to me this isnt a real filesystem but a filesystem addon? Do you have a link to this project?
