I really wonder how this replication approach works in practice without disclosing too much data on a system more exposed to attacks from the outside. In theory one could implement partial replication based on systems's bind identity. But in practice I have some doubts because in a really paranoid setup you don't even want to disclose replication meta data and intermediate entries of the tree structure. Ciao, Michael.
