A quick two-way rsync can be setup by using --update from the
secondary to the primary replica and then --delete from the
primary to the secondary replica.

Another file syncronization utility to look at is unison:

    "Unlike simple mirroring or backup utilities, Unison can deal
    with updates to both replicas of a distributed directory
    structure. Updates that do not conflict are propagated
    automatically. Conflicting updates are detected and displayed."
