FWIW I don't see any problem with having RRtypes for MAC addresses in the DNS.  
I am not an old DNS salt like many on this list, but seems there are many other 
RRtypes out there that have less interest.  I see the reference to the IEEE 
"Guidelines for use of a ...EUI-48" but for the sake of equal billing to this 
"other lookup table" it might be nice to add a reference/link to the IEEE 
Registration authority for OUIs, e.g.,  
http://standards.ieee.org/develop/regauth/oui/public.html , in your references 
section.

It's a MUST because master file format is a interchange standard.

RFC 1034

The standard format of master files allows them to be exchanged between hosts 
(via FTP, mail, or some other mechanism); this facility is useful when an 
organization wants a domain, but doesn't want to support a name server.  The 
organization can maintain the master files locally using a text editor, 
transfer them to a foreign host which runs a name server, and then arrange with 
the system administrator of the name server to get the files loaded.
