Thanks! I'll have a go at setting it up here.

In theory, IPv6 is available to anyone via the free, anycast
184.108.40.206 6to4 tunnel servers. I'm told that multicast is so wired
into IPv6 that the ISP's can't screw it up this time. So in theory,
it should be possible to do some kind of expanding multicast search
I notice that ntp.isc.org does have an AAAA record and answers ntp
queries on its IPv6 address. I wonder if the powers that be would be
willing to allow it to be a IPv6 multicast server. If I understand
things correctly that would require transmitting on ff0e::101, the
global multicast address with the 0x0101 ntp group id.
Anyone know what he rules of the road are for talking on a global
multicast? Is it essentially CB radio and one just keys the mike and
