While googling this, I found a couple interesting projects that may be useful, just in case anyone is interested. I just looked at them briefly.

You could probably also serialize Adaptor ops that occur after ec.saveChanges() using sth like the ERXAdaptorOperationWrapper and have some custom code dealing with conflicts. At least this would allow you to handle things in code, not in SQL.

My main concern with trying this with WebObjects would be, as others have said, trying to sync the persistence layers. Even if you could get it to work it would be horribly inefficient. In every system we've ever built like this we've handled the data sync at the database level through either OTS or custom replication. Hypothetically this approach should work with WO...the clients always write locally and the sync is database-to-database whenever a connection becomes available.
