Indeed, Doug does brings up an excellent point (and link).  However, as you
mention, we have to support Windows as much as possible, so providing some
sort of output option seems necessary at the moment (but do correct me if I'm
wrong anybody).

Of course, we could go the way of traditional Netcat and change -o to provide
a hex dump and not worry with any other output.  Since cmd.exe apparently
supports pipes and redirection[1][2], there is probably a program or option
equivalent to tee on Windows to provide something like the current -o.

And if there is a somewhat-standard Windows program for providing a hex dump,
in the fashion that Doug showed, dropping them both seems viable.

Thoughts?
