If I understand correctly your problem is the interactive ssh
authentification. You can replace this by using keys.

In a nutshell, on the sender side (that initiates the ssh connection):

ssh-keygen -t rsa

Just hit <ENTER> on all questions

On the receiver side (where the ssh server is running):
Copy the sender's .ssh/ into .ssh/authorized_keys of the
according user.

Now you should be able to "ssh remote-user at remote" and get a shell
without authentification. Same for "rsync -av /path/to remote:/path/to"
