So the source code is available, and anyone can run one. Stig wrote an I-D on how it worked, but this was not adopted by mboned (a shame imho). > As for transition of islands/hosts.

I think mboned is musing over IPv6+SSM or IPv6+embeddedRP as a way forward for multicast in general. Both streamline deployment, but have compromises. I think multicast support in tunnel broker services will vary with the provider. Probably worth looking for one that supports it :) -- Tim/::1 -------------------------------------------------------------------- IETF IPv6 working group mailing list [email protected] Administrative Requests: https://www1.ietf.org/mailman/listinfo/ipv6 --------------------------------------------------------------------
