Actually, no-one ever "applied" for inclusion in the list. The IPv6 capable nodes have all been actively searched for.
Kees van Eeten peridically runs a script that hunts for host names in the nodelist that have an AAAA record. When he finds a new one, het tells me and I try to make a binkp connect. If I succeed I add the node to the list. Some sysops may be on the list without knowing it.
If there is an AAAA record but no IPv6 connect, I contact the sysop and try to get him to get IPv6 working. Sometimes it works, sometimes it does not.
