Thanks for the info. I sort of get it. After looking around on the web  
it seems that SFTP ( which is already a part of openssh on our AMI)  
would be ideal. So now I just need to figure out how to set it up with  
a username and password for Springloops ( I don't think I have a way  
with Springloops to provide a keypair ).  I am guessing this has to do  
with the /etc/ssh/ssh_config file...

I think the ideal setup would be to keep the ssh login with no  
passwords/ssh keypair but perhaps create a special user for sftp with  
a password.. but I'm not really sure.
