Instead of why? how about using tail -f which is meant to solve this problem.
What you need to consider, if you do not like tail, is to develop some kind of daemon - usually written in C. You have an attached child process that leaves the parent there forever. If I understand what you have there.
PS: fflush() on every line forces disk I/O instead of buffered I/O. Since nc can produce an endless stream of data this change might help.
