I dunno, but my ATT installer mostly ignored the non-empty data
center rack (with a huge DIGITAL on the side) in my spare bedroom/office
and wanted me to kick up IE on my Mac cause his windows laptop
wasn't working.
"Er, IE was the second thing to go; sorry, I don't have
 the energy to update it every 3 days."

We got it working with Mozilla.  And it strikes me that he
may not have ever SEEN a datacenter rack.

One way that HAS allegedly been used has been to "catch" MAC
addresses that Netgear and LinkSys use.  I just told him I used
an airport (which does NAT).  He had no problem.
