Good point, let me slightly amend the model.  Whatever program
translates the domain names into ACE in the first place should perform
the prohibition at that time.  This function could be performed by an
enhanced DNS server that loads zone files containing natively-encoded
domain names, or by a separate program that creates zone files
containing ACEs.
