It's fine that your hardware supports multiple logins, but as long as there
is no one taking care of proper locking and caching mechanisms, concurrent
write access onto the same partition / filesystem will most likely lead to
data corruption.

In short, you're lacking software support for that kind of thing, so it's
very risky to operate this way. It's easy to hide some of the problems
(you probably don't need to remount if you know which caches to turn off),
but that does not improve safety in any way.

One common solution is to use a fileserver and a network. :-)
