Last time I tried SSHFS, I did have a few problems with moving files off sshfs mounts that led me into using NFS instead. If you do use SSHFS, be sure to check the sshd_config manual for the ClientAliveInterval and ClientAliveCountMax settings.
You can view my
setup notes and
the problem that followed.
