[6bone] best OS for ipv6 router.

[Abdul Basit]

Hello,

 What's the best OS to be run as ipv6 router ?
linux or freebsd (usagi or kame), from the facts
we observe kame is mature(more stable) than USAGI?
By the means of libc, does glibc supports most
of things described in sockets programming rfc's ?
or freebsd libc ? for example , i'm not still able
to get exim to listen on USAGI ipv6 sockets or bind9.
exim4 works on plain linux ipv6 support but not on  usagi
(as far as my experience).

 In short, for an instance if you want to run a super duper
IPv6 router what OS you should use(linux,freebsd) ? I'm not
talking about cisco routers.

take care
