Hello, I work as a teaching fellow in Telecommunications, teaching small-time network management and network programming. I am currently trying to learn more about multicast (IPv4 now, v6 later), in preparation for teaching multicast programming half way through the second semester. However, in the course we won't be connected to the internet, so I'm using my own home network to advance my understanding. I have a few questions about the current state of affairs wrt ISPs and content in New Zealand. 1) What broadband (and dial-up, for completeness) ISPs are multicast capable/friendly? Particularly Orcon, since our flat has just moved there. 2) What is needed to activate it at the users end (anything they need to do with mbone etc), or does the ISP deal with that? 3) Is there much in the way of content available? 4) Are there issues with NAT??? (I have a Nokia M1122 doing NAT, with Linux router/firewall behind it) Or alternatively, is there any documentation that answers these questions in the New Zealand environment. (If not, I'd be willing to help write/test.) Thank you all. -- Cameron Kerr cameron.kerr(a)paradise.net.nz : http://nzgeeks.org/cameron/ Empowered by Perl!
