The world is not black and white. My only point was that for this 
application I see no real difference between IPv4 and IPv6.

Yes, it occurred to me also (I always turns it off:).

If you promise not to let your rude reflex to show its ugly face
again, I will accept your apology.

That said, it does not mean I'm always right, and sometimes I'm more
happy being wrong than right.

Let's start over.


My position is to be able to run both ipv4 and/or ipv6 per user 
discretion. I don't think we have any disagreement about that.

Also, my position on how to make and keep latency low, an easy first
step is to make sure there is no other traffic than the transport of
the audio data and possible some kind of syncronisation/word_clock.
I don't know if this is all-important, but it is an easy step -- turn
off arp, dns, dhcp, ... -- since theese can possible interrupt the

If you tell us what the "Ethernet Soundcard" should do re. ipv6, I'm
