That is certainly one method. I would prefer one of the following options:
1) Configure SSH server on one of the machines (server), then use ssh 
tunneling+ rsync to connect to each client (only single exposed port, 
all traffic is encrypted, downside is overhead on the one machine 
picked. Some potential benefits from ssh compression.

2) Use a VPN, then just talk directly to the clients like they were on 
the LAN

If you do expose rsyncd directly to the Internet, then I would suggest 
that you restrict the source IP addresses if possible.
