He has the key, but to login to every machine to copy the file, he has to
type the password first.
Which is what he is trying to avoid.

If SSH without passwords is what your after why not use key based
authentication? Setting up keys is painfully simple.
Public key encryption
Generating keys for server A (the one with the data to be synced)
a@A:~> ssh-keygen -t rsa
Enter file in which to save the key (/home/a/.ssh/id_rsa):
Created directory '/home/a/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/a/.ssh/id_rsa.
Your public key has been saved in /home/a/.ssh/id_rsa.pub.
The key fingerprint is:
3e:4f:05:79:3a:9f:96:7c:3b:ad:e9:58:37:bc:37:e4 a@A
Tell Server B to Accept the key
1. Create a directory ~/.ssh as user b on B
a@A:~> ssh b@B mkdir -p .ssh
b@B's password::
2. Append a's new public key to b@B:.ssh/authorized_keys
a@A:~> cat .ssh/id_rsa.pub | ssh b@B 'cat >> .ssh/authorized_keys'
b@B's password::
3. Change permissions for b's authorized_keys file
a@A:~> ssh b@B chmod 0600 .ssh/authorized_keys
b@B's password::
Done

Ah well...
So much for skipping the research:
