IP address spoofing, yes. SSH private key spoofing, no, unless the
server's security is already compromised. (One would need the
*private* key of the host in question in order to encrypt packets
containing an IV to its public key and send them to you, which is
what sshd does to state its key to you. If this fails, you'll get
the "Warning, host key changed" message.)

There's a huge difference between logging in as root all the time
(on the console or remotely) and being *able* to connect as root
when the time is right.
