Going WAY back.  Comdex Atlanta, learly 90s.

The hotel I got stuffed in quite a ways from downtown, had 'old' 
hardwired phones, no RJ11 jacks.  But I was a REAL road warrior, I had 
my full tool kit of tools, jumper cables and the like.  I had the phone 
apart and my computer wired in and cleaning came in for some reason (I 
was running late and had not left for the show yet).  She freaked and 
called security.  I had to show management that I knew more about their 
phone system than anyone around and would put everything back.  SHEESH!

Then there was that 5 star hotel in Chicago where their integrated data 
jack could not support speeds faster than 1200bps no matter what they 
claimed (and I finally nailed the pbx rep on the junk they sold the 
hotel in front of the hotel manager).

It never ends.  We are always dealing with the lowest common 
denominator, GREED!  Followed by stupidity.

Scott Bradner, one of the original IETFers (his middle initial is 'O' 
and he LOVES to sign things with just his initials) once said at an IETF 
plenary session:

"The clue level in the Internet is a constant.  The Internet is growing 
geometrically.  I leave the math to you."
