Well there's still the option of accessing the metadata server the
traditional way over IP which is fully portable.  If some deployments
choose to opt-out of this facility I don't neccessarily think we need
to continue to invent further mechanisms. At some point you have to
say what's there is good enough and if people choose to trade off
features against some other criteria so be it.
