Well, the requirements are nearly similar. The key is the online/ offline
connection and which mechanisms you want to use for replication - 
database or
pgw. Your goal is to run offline clients that replicate their changes 
with the
master server. Thus you want the database to log the changes and do the
replication.

On the other side, we always have an online connection to share data. So
database replication is an option. It might be easier to sent SQL-Queries
directly to the local and the remote pgw servers.

That's the point, where began to focus on the "Peer Server" option in pgw.
Unfortunately we couldn't find any information yet and therefore have no 
idea
what kind of functionality "Peer Server" provides and how stable it is. If
"Peer Server" can be used to query different servers, we're done and don't
have to worry about database replication.
