It would be interesting if the problem hadn't been known about for the
last 20 or 30 years, i.e. since Unix systems started being networked in
large numbers.

This is exactly the reason Sun created NIS (formerly called Yellow
Pages). Using NIS a set of machines can keep user ids and other info in
sync. Nowadays LDAP is also used for this, as is Active Directory in the
Windows world.

Unfortunately for people with only a couple of machines on their home
network, these are usually too much trouble to set up, so the only
solution is manually to keep UIDs/GIDs consistent across machines.
