Subj : Going all in on IPv6?

Howdy,

Has anybody who has IPv6 thought about ditching IPv4? I'm very tempted to do 
it.

Today I tried tayga and couldnt get it going, when I stumbled upon jool. Jool 
was surprisingly easy to get going and has 2 distinct
benefits:

* Using a /96 from your network, it can map that to IPv4 address, so that that 
IPv6 clint can talk to an IPv4 system. It's all done in
kernel space, but it essentially proxies the connection.

* For the reverse, where you have a service (eg: a BBS) and you want IPv4 
clients to connect to your BBS with only an IPv6 address. It's
also done in kernel space, but it essentially is the same as NAT.

I guess for IPv4 connections, there is an additional hop and probably some 
latency, but for IPv6 to IPv6 connections its not part of the
path, so you get your line speed.

I'll throw some more load at it and see how it handles more pressure.
