I think there is quite universal agreement that we should not buy/reserve special IPv6 addresses as a group but rather everyone should obtain addresses from their own local internet provider and we should arrange some way to distribute the list of IP addresses in use amongst the participants. This makes it unnecessary to use a tunneling system which simplifies the network and makes the routing much faster (no need to go via UCSD anymore!). And these addresses are normally included with your internet service for free. Rob
