Hullo all. I'm working on a talk, and would be interested to know what people think is good about tunnels as an IPv6 transition technology, and what people think is bad about tunnels. It would probably be best to let me know off-list :-) but I'm happy to summarise back to the list. Any references you have to useful papers, articles, discussions etc would also be appreciated. I'm looking for both general problems and advantages, but also advantages and disadvantages specific to particular tunnel types. It would also be helpful to know from what perspective particular things are good or bad, in so far as it isn't obvious. A carrier has a different perspective than, say, a home user, who will have a different perspective again to an enterprise user. Many thanks in advance for your input. Regards, K.
