Even if Boeing isn't party to the ARK story, perhaps some of our
business partners are. Perhaps Boeing and some of its partners are also
party to the (fictional) Aerospace Research Knowledgebase consortium --
we can be party to more than one party interested in the letters ARK.
When we convey a URI like http://boeing.com/ark:/120025/654xz321 to one
of our business partners, how are they supposed to tell if it's an ARK
identifier or something else? Perhaps it was intended solely as a
globally unique identifier, with no intent to  support dereferencing.
When the business partner is cautious and makes a metadata request, but
gets no helpful response (by design or by network outage), how do they
divine the intent of the URI?

What is the problem if you do?  If Boeing isn't a party to the ARK
story, then it is under no obligation to behave according to that story
when it handles GET requests.

And of course, in a way parallel to the WEBDAV story told elsewhere in
this thread, a cautious user of ARK-based URIs will make a metadata
request (via an empty query string) to confirm that they have an ARK URI
before proceeding based on that assumption
