Hi,
First of all: Thank you ppl of HE for providing me with IPv6 ... I'm a happy free Usenet IPv6 leecher now

But then to my idea:
I think better internet connections with IPv6 tunnels should be rewarded. For this you should implement a speedtest. (Maybe serveral, for global coverage) The test is simple: Every Mbit over IPv6 tested should be awarded 1 point for downstream Mb and 3 points for every upstream Mb.
You provide the speedtest, we take the test from our IPv6 enabled hosts. Only 1 test per tunnel should be allowed. But there should be a reset option, for people who didn't configure IPv6 just right.
The test should be available in textmode browsers (I'm not installing a GUI on my servers ofcourse)
Example:
I have a 100Mbit FD connection on my webserver, which is tested and gets 80Mbit downstream aka 80 points and 75 upstream for 225 points. At home I have a 90/6Mbit cable connection which would award me 85 points downstream and 15 points upstream. (Given that are my actual results)
Ofcourse, the max total points should be higher to maintain a balance. People who have 1500 points now, should be able to increase stats to 2000 points with this test.
Just an idea. Let me know what you think of it.
