You mean "generic" as in a replication system that can do asynchronous
master-slave, asynchronous multimaster with conflict resolution based on
timestamps, system priority or user defined resolution stubs, can do
synchronous predicate locking but also does support thousands of
asynchronous, partial replica (salesman on the road), and last but not
least can run as a synchronous cluster in a LAN segment. All the above
can of course be mixed together ... like a central cluster of 8 load
balanced, fault tolerant systems, with async multimaster replica in all
external branch servers, partial multimaster replica for the road
warriers and some slave leaf nodes for reporting.

If you can present a prototype for the above, I am sure that we will
change our opinion and finally settle for one, builtin replication system.

What specification?
