Maybe I'm the only person who doesnt understand DNS well enough to figure
out how this would be implemented, but I dont thinks so.

Could one of those proposing TXT records, help the rest of us by ...

Sharing a code-fragment that might be used to find a server for example for
a URN with a Naming Authority of "xyz.com". It doesnt have to work, as long
as the basics are there. Using CNAMEs or A records it would just be
calls to gethostbyname, and using a well-known port.

Also - posting an example of a TXT record from a dns configuration
file would be usefull.

A couple of points on previous messages.

I think replication can be done with CNAMES and A records, you use
the CNAME to point at the right site, and then A records at that site to
specify the replication.

Sopmeone mentioned the problem of "well defined ports", personally I'd like
to see whois++ and URN->URC resolution on different ports, the URN->URC spec
is going to be much simpler, than I expect whois++ will become as it grows.
If they turn out to be the same then we havent lost anything putting the
same services on two ports is easy, but if we turn out to want the defaults
on the URN->URC server to be different, i.e. default to returning a URC in
an appropriate format for it, then we will have lost if we put them
on the same port.
