Mac OS X 10.5 and earlier use a different mdns implementation that was
not open sourced.  That said, all the mdns backend does when printing
is execute the backend that corresponds to the protocol being used -
ipp, lpd, riousbprint, or socket.  Any back-channel support will come
from those backends and not mdns itself.
