 >>We used to use "gateway" instead of "router" (and a few still do), and

i lik the fact that if you type getaway by mistake you get what people
are trying to do when they are routed ...

i also like the fact that MOST fancy things we do in traffic treatment
(firewall, diff/int serv, header compression, checksum) ignore this
layering rubbish idea and look at the whole packet and the whole state
of the systems where you need to......creating articifical monitor
security/concurrency boundary crossings in component software was a
terrible thing, and many modern OSs have got a long way away from
it....

on reflection (pun intended):
layering is a clothing methodology for people who live in fractal climates
not a design pattern for correct or efficient communications
systems....
