Thanks for pointing that out.. it's a great lead.

This link from 2006 mentions somebody looking for openbsd's version netcat
http://cygwin.com/ml/cygwin/2006-04/msg00490.html
"
.....it's an openbsd fork off the original netcat that I
never heard of before.  Cool.  I'll see if it builds for cygwin.

    cheers,

I found it here now ported to Cygwin-
http://www.daemon.de/Netcat

doing -? and -h ,  I see  -X proto

It needn't be in place of the current nc

We've got the GNU one ported too, - mark found the modification to the "configure" file to get it running. 

So I use ncgnu.exe  ncopenbsd.exe

The author of openbsd version of nc ported to cygwin posted on here in March 2011
"OpenBSD version of netcat ported to cygwin"
http://readlist.com/lists/cygwin.com/cygwin/10/50653.html

But looks like adding it to the cygwin packages didn't happen.

I would guess that maybe the threat of pulling the current nc, and replacing it, could be a bit of a disincentive to somebody looking to become a cygwin package maintainer of the openbsd version of the cygwin port.  So maybe that's why it didn't quite happen, but that's just a guess. Anyhow since they are different versions, I suppose they could live alongside each other/ both be available.
