I've tested two Linux distributions in an IPv6 environment, Ubuntu
10.04 Server and CentOS 6. Granted I've only been testing services for
a few months now but I've found that both can deliver adequate service
delivery via IPv6. I did run into the connection tracking issue with
CentOS 5 and you are correct, it is fixed in 6 (its also integrated
into the ufw program so setting-up host-based rulesets are very easy
in an IPv6 world).

In my case, its mainly testing both platforms but I haven't discovered
any significant issues with either, and this is running basic services
(DNS, HTTP, SMTP, a few little python JSON servers) over a 6in4 tunnel
on each platform.
