We did have a chat about that in IRC and it was pointed out that Netcat might not be able to make to do it without a script. At least it was some help in enabling you to find socat ;)
I really must get into IRC!
I did already know of netcat (I'd forgotten all about it though) from playing with it for sending disk images over networks. So it's nice to have that put back in front of me anyway, even had it not pointed me to socat.
"apt-cache search netcat" is what found socat for me. I was actually looking for the BSD alternative to the included one. There was also netcat6 which is GPL licenced, has IPv6 support as well as IPv4, and is at v1.0.
