There's a better known case, and that's PalmOS "PalmSync."
It does fairly much the same thing as Lotus Notes(tm).
In both cases, they are doing something that works reasonably well for
data that looks somewhat like "documents." Conflict resolution at the
"document" level is something that users can handle pretty well by
hand.
Unfortunately, for data that's more at the "hordes of little facts"
level, conflict resolution is a tough problem :-(.
