It has occurred to me that the name on my shirt's tag contains some
structured information. That doesn't make it particularly well suited
for use as a computer network routing key. Or suited at all.

Intentionally crashing the moon into the earth is a new idea. How far
should we run with it before concluding that it not only isn't a very
good one, considering it hasn't taught us anything we didn't already
know?


Van Jacobson had a similar observation vis a vis TCP and PPP header
compression, why keep sending the same bits back and forth over a PPP
link for example? Why not just an encapsulation which says "same as
previous"?

Now, how can that be generalized?

By observing that within a restricted subset of a problem domain there
may be usable techniques that aren't portable to the broader problem
domain. This is not news, and your comments have not bounded a subset
of the routing problem domain in a way that would make a discussion of
names as routing keys interesting.
