People are just saying that the pieces you claim aren't available actually are. I'm using openssh (client and server) with passwords and rsync in OS2008. I use rsync to sync up collections of documents, backup images, etc all over an ssh connection. (often over a openvpn connection also if I'm on the move).

I just installed be becomeroot deb and openssh client and server package. Then became root and changed the password for root and user. Then installed rsync and cooked up some shell scripts for different things which are then called from Kerez or osso-statusbar-cpu.

Not sure about dropbear as I've never used it.
