Hi,

    >> Probably what can  be standardized is a method for signalling and exchanging the ICE candidates so that end nodes can mutually push the data to the other.

    > Have we already established that you do need ICE?
    >I agree that in a NATted, IPv4 environment ICE is a good way to obtain useful address pairs.
    >Can you run your application in a clean IPv6 environment?
    >Then you don’t need ICE; everything just falls into place.

I am not going to get involved in a discussion about that, because it is not CORE specific, but IPv6 is *NOT* going to remove the need for NATs :)

Regards,

Christer
