The problem is that we can't reliably give that information. For example, fuse 
filesystems on Linux may be both local and remote. What's worse, some local 
fuse backends may provide worse API than some remote filesystems (locking, 
etc.)

Unless we want to make this a tri-state: definitely local, definitely remote, 
could be either.

I'll block any patch that tries to give a certainty where the lower level 
doesn't give us certainty.
