Not always...sometimes the r* commands are blocked at a firewall, but not
a telnet. Also, the r* commands can be blocked with rhosts files. Also,
at the moment, my connection from home to the net is by way of a "SLiRP"
setup on my shell account at work - it presents a PPP server to my home PPP
client, but my home system isn't really on The Net. My net accesses
appear to come from the work system I dialin to. At any rate, it can pass
telnet, but not the r* commands through.
At any rate, specifying a username isn't part of the telnet command - it's
frequently part of the information conveyed with telnet, but not part of
telnet itself.

Hmmm...I bet you could do something like this:
% cd /usr/src
% find . -type f -print | xargs grep -f 'getpwnam'
or something similar to get a list of places to start looking (for the
daemon side username validation?).
