> Due to these serious problems rlogin was rarely used across untrusted networks

Good you finally pointed out the most important thing

"rlogin/rsh is insecure across untrusted network"

This is QUITE a difference between this and "rsh is insecure. period"

rsh is as secure as the communication channel. If it can be considered 
secure - DO USE rsh, because it's fastest as it doesn't have any 
encryption overhead.
