That's a shame :S

It is hard. But it's one of the main reasons why Lotus Notes used to be
so popular. 
It does this.

Exporting and Importing do this to a very limited extent.

The big issue is how to handle replication/save conflicts (Notes Term)
which you must have done in ZEO...

What happens in ZEO if two clients both change an object at the same
time?

Normal Zope is very bad at this... for example, what happens if two
people try to edit a Wiki page at the same time? Someone looses their
changes (whoever submits first...) which is not good :(

hmmm....
