I don't think this can handle any number of connects, as . $0 will quickly segfault your shell, due to a stackoverflow see here for more details.

@professorfish . is the same as source. So basically it sources itself.

I suppose that nc is from BusyBox. The GNU netcat requires -p switch too. And with my bash 4.2.42 there is no such error if you remove the space before <<<.

If you mean nc -l12345<<<Hello, that doesn't work. nc needs the space between -l and 12345, and removing the space before <<< gets bad file descriptor from Bash.
