No, should be fine. Unrelated to /var/snd, if you use Rsync with --delete and the directory names change it won't delete the differing directories which is kind of annoying.

E.g.

Master:
Folder 1 with a new name
-- File 1
-- File 2

Slave:
Folder 1 with old name
-- File 1
-- File 2

You end up with:

Slave:
Folder 1 with old name
-- File 1
-- File 2
Folder 1 with a new name
-- File 1
-- File 2

Probably unnecessary for Rivendell but if you want master -> slave near "realtime" replication Syncthing works really well. Just remember to set your master folder as a master in the settings so that changes on the slaves aren't replicated.

It does have overhead as it hashes all the files but it also means it can instantly copy duplicates to different directories by using files it already has (even partial blocks which is obviously quite rare in audio).

I have been puzzled by why I could not get rsync to delete when using the --delete option. I learned that if you use /*.wav that the destination will not delete its extra files (as used in the Rivendell rd_audio_sync script). If I remove that from the string, it deletes like expected.

Examples:
rsync -av --delete master::rivendell/*.wav  /var/snd.standby

The above copies all the files from master to standby fine but will not remove any files in standby that do not exist on the master, whereas the following does because it requests the whole directory, not individual files:

rsync -av --delete master::rivendell/ /var/snd.standby

Is there any danger or undesirable consequences to replicating like this?
