In my professional environment, user's laptop have small (but fast ;-))
storage and a local home directory (centOS7).
They use sshfs to reach a central storage for most of their needs. This
central storage is secured (ceph replication + daily backup).
It works also from home but, of course, with lower performances behind
an ADSL box.
No problem with closing connections.
