If security is not a concern, write a simple script that accepts the 
password and provides it to sshpass (which isn't packaged for Fedora as 
it's a huge huge security nightmare): http://freshmeat.net/projects/sshpass/

e.g.:
[sam at sam ~]$ export SSHPASS=mypass
[sam at sam ~]$ sshpass -e ssh unixdb2-vm
[sam at unixdb2-vm ~]$

In your case, you'd want something like "sshpass -e scp /etc/hosts 
orion:/etc/"
