named pipes, posix ipc, signals, etc. There are quite a few existing communications methods that can be used for this purpose.

OK, and how do you format the data you send across, or find out which functions the daemon supports and trigger them?

Classic sysvinit or BSD-style init doesn't rely upon this sort of functionality at all. Just some simple scripts. No need to complicate it any further. A few signals are all that are needed.

Simple scripts? Have you looked at the shit in /etc/init.d in a modern linux distribution?

  $ wc -l * | sort -n | tail
   274 exim4
   286 apache2
   290 dnsmasq
   298 nfs-common
   350 clamav-freshclam
   364 udev
   386 checkroot.sh
   420 clamav-daemon
   465 clamav-milter
  9893 total

If you look into these, you'll find tons of near-duplicate code between scripts, and frequently every script reinvents the wheel in one way or another.
