So write it. It wouldn't be terribly difficult. I don't think it'd be
terribly popular (so you won't be able to talk someone here into doing it
for you) but you could grab an idea for the communications & logging from
syslog (using a daemon & a socket) and just instrument the right parts of
the kernel to write to the socket. You'd have to write the daemon & write
a bit of code in the kernel. It would be a reasonably simple project.
