but in order to run netcat on both ends, you have to have logged in
anyway. besides, isn't it possible to get those programs to use ssh
instead of rsh rather easily?

ssh can be compiled to offer cypher=none, but most people leave that
out either for fear that having such a thing would cause people to use
it, or because rsh can already provide no encryption.

i think we are getting far afield of the actual issue here, which is
that netcat is a good thing to have, and i think we both agree on
that. there will always exist times when all you want is to blt a
large chunk of data from machine a to machine b and all you want to
know is that it got there. when i'm dumping (and gzipping) my /usr
partition to another machine for backup purposes, netcat fits the
problem very nicely.
i don't even remember what the original issue was.
