We do something similar, except that we use unison rather than rsync. This tool is a two way rsync, it deals with collisions and replicating files in both directions at once. Very nice. Look for it in the ports tree. This has some advantages for us since we distribute load across several machines and have a cluster of machines which all replicate to each other. The data is such that collisions are almost never a concern.
