the linux kernel does ignore the ::/0 route if it is in forwarding not, I guess this is since it is asumed, that the user knows what he is doing and does not want to do that. You can use 2000::/2 instead.

it is by intention, yes.

yes it deoeds on the ipforward setting.
BTW: i am working a bit on net-tools and ipv6, like:
calista:~# netstat -tl Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State tcp 0 0 *:1024 *:* LISTEN tcp 0 0 *:5269 *:* LISTEN ... tcp 0 0 calista.inka.de:domain *:* LISTEN tcp6 0 0 *:auth *:* LISTEN tcp6 0 0 *:ssh *:* LISTEN tcp6 0 0 *:smtp *:* LISTEN
i am not yet sure about the wildcard address and the port separator, but I like the tcp6 :)
ifconfig may get a more BSDish look, also:
# ./ifconfig eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500 metric 1 inet 10.0.0.3 netmask 255.255.255.0 broadcast 10.0.0.255 inet6 3ffe:400:4f0:ffff::3 prefixlen 112 scopeid 0x0<global> inet6 fe80::2e0:7dff:fe92:1f0b prefixlen 10 scopeid 0x20<link> ether 00:e0:7d:92:1f:0b txqueuelen 100 (Ethernet) RX packets 2581434 bytes 1632512018 (1.5 GiB) RX errors 0 dropped 0 overruns 0 frame 0 TX packets 2031678 bytes 1202569629 (1.1 GiB) TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 device interrupt 9 base 0x9000
