This problem has been discussed at some length in various of the IPv6
working groups (I can't even recall which ones - they all blur
together ;) and by Sebastien Roy, Alain Durand and James Paugh in
draft-roy-v6ops-v6onbydefault-01.txt
By the way, my IPv6 connectivity to nether.net is actually better than v4:
ping -c 10 -q puck.nether.net
PING puck.nether.net (204.42.254.5): 56 data bytes
--- puck.nether.net ping statistics ---
10 packets transmitted, 10 packets received, 0% packet loss
round-trip min/avg/max = 214.071/251.098/289.917 ms
ping6 -c 10 -q puck.nether.net
PING6(56=40+8+8 bytes) 2001:468:901:1:203:93ff:fed6:dfcc -->
2001:418:3f4::2a0:24ff:fe83:53d8
--- puck.nether.net ping6 statistics ---
10 packets transmitted, 10 packets received, 0% packet loss
round-trip min/avg/max = 161.488/174.261/217.397 ms
