Sure - a situation where a system needs a low-bandwidth/low CPU-use 
shell-based communication protocol and sniffing is not an issue for 
whatever reason.

I agree -- SSHd over telnetd anyday.  However, you asked for a genuine 
scenario where telnetd could be legitimately used and they do exist.  
I'm not saying that it's the greatest security ever, but encryption != 
security, but it can be used as part of a plan to secure a network in 
the right circumstances (most circumstances).  What security tools one 
uses depends on what the situation is.

SSHd doesn't come with a 0-cost basis.  It's relatively low cost, but 
there are circumstances where resources may not be available enough to 
justify it's use in that situation.
