Thread:Talk:Requests for comment/Zero Architecture/Zero requirements/reply

I think dfoy would be the best person to talk about requirements, but from what I know, there are some good reasons for it: a) navigating to a zero.* domain always reports free/non-free banner, b) unlike m.* has no images, c) allows carriers to do URL filtering in a more precise way, d) all links get instrumented to ask for "navigate to pay zone" confirmation. At the same time, we are trying to get all new telcos to get m.*, even though we might still be under contractual obligations to provide the zero domain (my suspicions, not hard facts).
