If the machines are very remote then rsync from a cron job is probably 
the best way, yep. Look at the ssh manpage about using public-key 
authentication so you don't need to type the password (simply create a 
key with no password).

If, however, the machines are really close together you might like to 
look into using NFS instead. That was you only need to keep the files on 
Sarge1 and mount A onto Sarge2, which will _always_ have the latest version.

HTH,
Chris
