Not sure the exact implications of the keep alive, but I have not yet
seen it send traffic back and forth without input from the terminal,
both dialup sessions and a firewall connection get dropped without
terminal traffic.
Regarding large traffic delays on a network. Thus far I have
pretty much
been able to disconnect most users with floods to the network and/or
sometimes a really bad connection will just drop the
connection. Suppose
that is better than telnet and there for man-in-the-middle attack
prevention.
Could also be used as a DoS though.
