I don't think you have a technical problem.  You have an organization 
that is not in control of its assets.

Although there is a draft in the IETF, the problem is that "there is 
a draft in the IETF," and not a final, refereed/reviewed document 
that can be cited as a reference.  Efforts to help this document get 
done would be a good step.

Once there is a document of some weight, this can be used to inform 
the organization about at least one detail they should undertake to 
behave better on the network.  This step is usually done via either 
evangelizing as an outsider or consulting for the company.

Sounds like this company is in need of an edumackation.

Think glocally.  Act confused.
