If not what other options are out there? For slony, depening on how your application is setup, you might be able to have each site write to a set of local tables that are then replicated back to a single office. The database at that office would then need to merge all of that together and publish it back out via a different table. Your only other option is one of the command-based syncronous replication schemes, but you have to be very careful about what commands you issue with those. They also tend not to handle communication interruptions very well, making them ill-suited for replicating over a WAN. -- Jim C.
