I also don't understand from the website if this is a real filesystem (mounts in the namespace of the OS, works with any program etc) or o userspace utility, something like an explorer/finder plugin.

Can anyone shed some light on that? Thanks.

From what I can tell, it's neither: it's just a directory (and subdirectories) on the existing filesystem; like Dropbox.
