I think, rsh is quite obsolete

Exactly.

I use telnet over OpenVPN tunnels (strictly between the ends of the 
tunnels, not beyond) and it's much faster than ssh, since telnet can be 
compressed by OpenVPN while ssh, being "randomized" (encrypted) already, 
does not compress too well, if at all.

Also, we have a protected environment where encryption gives us no 
security advantage, while plain text protocols are much faster than ssh. 
With ssh we get transfer times that are unacceptable, while plain text 
transfers will hit the bandwidth ceiling and complete pretty quickly.

Leave the cleartext protocols alone, they're good tools if you know what 
you are doing.
