Create a fifo with mkfifo, and have dd_rescue write to it. On a separate 
screen have netcat read from the fifo.

Be warned: a fifo is not seekable (btw the | you are using with dd is 
actually also a fifo internally), since it's not seekable I can not say 
how it will work. dd_rescue does seek the output file, especially when it 
finds errors.

It's likely to only work if there are no errors in the input, in which 
case why are you using dd_rescue?

I don't know why you want to use netcat, if it's because you have no 
available storage for your dd_rescue output, instead of netcat (which will 
not work since it's not seekable), use a remotely mounted filesystem (smb, 
nfs, sshfs, etc.).
