I have never used FileReplicationPro but looking at what it offers it reminds me of GlusterFS. I use GlusterFS for all www data of the domains I host. I don't use jet GlusterFS for IMAP/POP storage for all domains I host. Only a small subset of the domains I host have GlusterFS for IMAP/POP but so far it works without issues and I will soon or later migrate the other domains to be on GlusterFS as well.

The setup of GlusterFS is ultra easy (compared to other clustering FS solution I have seen) and it offers some very nice functions.

In the past I have burned my fingers with older GlusterFS releases when I have tried to use it as storage for IMAP/POP but the later 2.0.x releases of GlusterFS are more stable.
