Indeed.
There's also a class of clients for which implementing the
full horror of replication may not ever be appropriate.
Consider something like a voice mail system.
It wants to know immediately a new user is added
to the e-mail system's directory, in order that it can
answer their telephone for them. Persistent search
provides a convenient and easy to implement
way for such a client to find
out about new entries in the directory.
