IPv6 Tunnel Brokers?

[Eric Crist]

Hey list,

While my ISP is rather geeky and more than willing to give me an IPv6  
tunnel to the internet, there seems to be a large number of routing  
problems upstream from them that prevent us from accessing the  
majority of the IPv6 net.

So, I ask two things really.

1) Does anyone know of an ISP that'll give me a /48 or /64 they'll  
route across a gif tunnel?
2) What could I do to help remedy this routing problem?

Thanks!
