I've used this technique with several live applications in environments 
that had stringent requirements for security and reliability. I rely on 
ssh for security with respect to remote access over the network. I don't 
know if screen introduces any new security issues, but it's generally 
considered to be reliable. I prefer to use tmux instead of screen, but 
AFAIK they are quite similar.
