I was not so much concerned with the implementation of the distribution,
but merely with showing the analogy to /etc/services.

The need for such a system comes from the bandwidth you can save by
replacing a lengthy string with a well known number. Nothing really new.

Well, this again is a bandwidth issue. I still think that time(2) provides
the most useable format, maybe with an added fraction. At least for inter
machine communication. I doubt that the host names on the way are that
important. With several hops you will often know which host is where. If
not, then optionally add it (separated with a colon) to each timestamp.
Optionally.
