tor over ipv6

[Udo van den Heuvel <udovdh@xxxxxxxxx>]

Just a thought:

With the previous tor experiences in mind w.r.t. services blocking me, I 
thought about IPv6.

I could run a somewhat open relay on an IPv6 number via a IPv6 in IPV4 
tunnel if I (ever) get that to work. My isp (xs4all) offers such a 
tunnel for free and a (small?) IPv6 subnet to go.

a) does tor work well with IPv6?
b) how is the added value for the tor network? (IPv6 vs IPv4?)
c) how well would the IPv6 setup work w.r.t. my IPv4 number(s) being 
blocked by whatver server/service/etc.
d) any actual operational experiences here?

Anyone?

Thanks,
Udo
