Nope. I'll try another way

This example is back to the functionality that (x)inetd would provide.
The idea being that grep* would act on the data that came in the TCP
connection and send the matching lines out the same TCP connection.
*grep is just a hypothetical example here.
I'm not sure if that is even possible, although
you can't rule out
creative uses of dup2() etc...
