I was also thinking about a setup using multicast simca-name-server
discovery. For this a client or server broadcasts a request and
name-server responds by sending it's ior and other relevant information.
The TTL of the multicast message defines its range and can cover as much
as the local domain as the rest of the Internet. So you have some
control of where you expect or want to find name-servers. Also I think
this is nice for name-server chaining. name-server requests and receives
responds at periodic times (like dns does) to discover dead or new
name-servers. Maybe also clients and servers respond on client broadcast
so client knows what is out there.

Drawback of multicast is that router needs to support it. Although I
believe most of them these days... (?)

What do you think?
