Possible to print message(s) before login?

[Derek Frye]

Hi,

Is there a way to print a message before the login prompt or after the 
login prompt but before the password prompt? This way unauthenticated 
users can see a small message (like "Hello!").

I looked through the source for version 4.2 and couldn't find where the 
login strings are constructed and sent (except in the client software 
portion). Maybe all strings (like "login: ", where users enter username) 
are generated and encrypted in the client software in response to server 
packets (non-strings)? So is there even a way to send strings before 
successful authentication?

Maybe this would violate the design of openssh?

Thanks,
