I don't use sshfs on a regular basis, but it definitely has caching:

http://linux.die.net/man/1/sshfs

The caching is on by default, it looks easy enough to turn off, but I
imagine performance would be impacted.

All network file systems are more fragile than all non network file
systems, so I guess technically yes.

Technically correct, I guess. There were/are explicit riders in Australian
copyright for proxy servers (only in the education sector, I think).

But the computer is mostly a copying machine, with a keyboard and screen
attached. Even on a local file system, the files will be copied into ram
for the file system, then copied into the users memory space to edit the
files.

IMO these are both spurious claims to stop you using sshfs.
