Vincent, did you actually READ my post before writing yours? I said quite clearly that the device would be MOUNTED. I.e. it would have a file system on it. My point being that if you remote mount it as a block device, then the file system on the local machine caches (i.e. fast access) while the remote machine provides (semi-)fast block access across the network. diversity is a good thing.
