In my view Internet should be designed to be a) fast, b) reliable and c) 
cheap.  The extra crud in the protocols makes achieving these goals harder 
than it could be.

See much diversity and heterogenity in the IP protocol?  See much 
diversity and heterogenity in the Ethernet frames? 0800-45, heh.

The lesson seems to be that simple technologies survive and prosper while
over-engineeried everything-and-a-kitchen-sink designs like OSI fail.

BTW, I didn't say anything about L2 framing. What I said is that ARP is an
unnecessary complication, one more thing which can fail, can be attacked,
and which introduces complexity into equipment and software (and *that*
complexity costs real money).  There's nothing God-given about that.
You're skewering a straw man.
