Yes

The big data with user-level subsets is our typical usage, but our
users subsets will often overlap.  So while our users can only see
some data, it does not mean they are the only ones who can see and
change that data.

Our concerns with replication in this situation are mostly security.
Either a record level security or a way to secure server replication
so that it requires the use of a filter and have the filter able to
perform a security check, would be great for us.

Jay
