I'm not an ISP (I just play one on TV), but I have an IPv6 link through a 
tunnel broker (Hurricane Electric) on my FreeBSD router and it advertises 
routes to my LAN.

Average ping times to my tunnel peer from the router are just over 30 ms.
Ping times to ibctech.ca from a workstation on my LAN (running IPv6) were 
about 70 ms.

I'm using an asymmetric cable connection with 5Mbit/s down and 768Kbit/s 
up. I was able to mostly saturate my connection downloading your big 
file. Download speed on the workstation (unscientifically reported by 
Firefox) got as high as 580KByte/s with 570KByte/s sustained much of the 
time. That's as fast as I can ever download anything using IPv4. The 
speed did dip to 200-300 KB/s a couple times but it went back up above 
500 relatively quickly.

HTH,
