Yeah, the one on the (Soekis) example was pretty small. So far none of
of the replies have indicated that anyone on here has experience beyond
an embedded system.

Mostly I started this thread because there have been a few with people
discussing implementing NTP on embedded microcontrollers, arduino, etc.
and I was thinking of doing it from the other side (turning a nice-ish
server into a rock-solid timekeeper)

Thanks so far everyone. Really impressed that I already managed to get
4x replies so quickly :)
