Sorry, I didn't realize that the SSEC/SDI "cat" utility was
proprietary.  (No, we don't have access to that source).

I'm afraid there's no optimal solution.  Some less-than-optimal
alternative include the following:

    1.  Do what you were planning on doing with KEEPALIVE and the
        writing of the NUL byte and pray that the utility and the 
        connection never dies.

    2.  Put an LDM on the computer that's running the SSEC/SDI "cat"
        utility.  Configure the utility to write to a FIFO and an LDM
        ingester to read from it.

    3.  Pay real money to SSEC to send you a modified utility.
