This was my point exactly, in an earlier message, being behind a corporate
firewall myself.
DNS has it's merits as the storage, transport and replication facility. There
are clients that exist to access it, it's free, all those good things. It's
not a good DB in general ("give me all the Rock albums, from 1967-1990, by the
Rolling stones") but I don't think this is a design goal of the cd index
database, anyway.
We haven't really talked much about LDAP. It has replication for free too, and
it's probably an equally or better suited wheel to re-use for this purpose than
DNS is. I wholeheartedly agree with Alan Cox that we should not re-invent any
database distribution or replication protocols to support this cause, but let's
not limit ourselves to DNS. Neither DNS nor LDAP protocols are generally
passed through corporate firewalls, so no matter what the underlying database
and distribution mechanism is, the access protocol, I believe, should always be
HTTP in order to make it universally accepted.
