Interconnects

A bunch of us are thinking about multihoming solutions for IPv6. For this purpose, it is useful to know a bit more about how actual networks (rather than the ones existing only as ASCII drawings) interconnect. So: - What are the 12 - 18 most important interconnect locations in the world? MAE East, the Ameritech, Sprint and PacBell NAPs, PAIX, LINX and AMS-IX come to mind, but from where I'm sitting it's hard to judge whether others are important or marginal. - To how many of them do typical tier-1 and tier-2 networks connect? - Using private or public interconnects?
