  That depends on how you interpret the sentence in RFC 2132:

         Option codes 128 to 254 (decimal) are reserved for site-specific
         options.

  My interpretation for this is different from yours, since RFC 1497
says:

         Reserved Fields (Tag: 128-254, Data: N bytes of undefined
         content)

            Specifies additional site-specific information, to be
            interpreted on an implementation-specific basis.  This
            should follow all data with the preceding generic tags 0-
            127).

So I think it's fair to assume that "site-specific" is used as an
alternative word to "implementation-specific". In fact, Etherboot
defines several vendors extensions in the documentation:

http://etherboot.sourceforge.net/doc/html/vendortags.html

Anyway, how can a local administrator use the site-specific
information if no (client) implementation supports it? ;)

  That's right, but I don't think they will accept an
implementation-specific feature.

  Therefore, if the Etherboot developers have no opinion, I'll pick an
arbitrary code which is not used by Etherboot at least for now.
