You're right about this not being perfect - I'd go further - it isn't 
workable in the long run.  Consider the situation of one entity's 
subdomain matching another entity's domain.

I think that part of the solution here is a directory service/mechanism
such as that which can be provided with whois++.  Proper integration of
such a service with key management and mail systems should eliminate this
problem - and should do so properly. 

This only really connects with firewalling in that it presents issues
similar to those raised with getting users across a firewall (user 
training/knowledge/understanding).

As a VP who isn't in charge of Finance, I agree.... <g>
