I have written a filesystem over Fuse to access a remote pseudo-NAS (the French "Freebox V6", I'll soon publish it as GPL3… when it's a little bit more polished!).
The NAS is connected to a home ADSL, thus data comes down at the upload speed of ADSL, which is at best 1Mbps.
My mount works fine (read-only at the moment), but Nautilus sees the mountpoint (and all sub-directories) as a "local" filesystem and tries to make thumbnails.
As I have a directory full of images, this is quite horrible, because Nautilus then opens ALL the images to try to display the thumbnail.
I could switch the Nautilus preferences to "Never" for thumbnails, but then I'll loose thumbnails on my "real" local filesystem.
So the question is: with the preference "Only for local filesystem", how can I instruct Nautilus that my mountpoint is in fact NOT a local mount so that it will stop trying to draw thumbnails on that specific mount, but continue "thumbnailing" on mounts that are really local?
Edit note: the same things happens if you use "standard worldwide" mounts such as sshfs, davfs,… as long as you mount over a relatively slow network (ADSL) and have images/movies on your mounted tree.

I suspect this isn't currently possible - I've been searching for solutions with sshfs based mounts and been unable to find any.
