Another typical environment is two spouses or parent and children where
only one of them is really all that into logging dives and wants to log the dives
for everyone separately, with separate cloud accounts as well. So you and your
spouse can look at your own dives on your phones, but only one of you sits
at the computer and downloads the dives from the dive computer(s).
