I'd say you are.  End users frequently don't know the layout of their 
carrier's networks, and I certainly wouldn't expect ARIN to be interested 
in that level of detail.

What's next?  Are you going to ask if I'd require that your router have 
dual power supplies from different UPS's, or that if they don't have dual 
power, you have a router per transit connection?

It's a shame ARIN's auditors don't hang out here (or if they do, that they 
don't jump in and end these sorts of "what if" circle-jerks).  It's a 
simple enough question...have they already seen applications for IP/ASN 
resources where the applicant was required to be multihomed and their 
connectivity was one leased line and a GRE tunnel with BGP to a second 
provider.  Was the request approved?

How many providers will even provision such a service?
