@fdevillamil Thanks for the notes!
Re 1: adding rel=me is a manual step right now if you're editing your own HTML. However as @barnabywalters pointed out, this is really "exposing important problems further up in the chain" (http://waterpigs.co.uk/articles/indiewebcamp-signin-ux/) It's also entirely possible that an identity hosting provider like about.me would add the markup automatically.
Re 2: This is not quite accurate anymore, given my recent work on distributed IndieAuth (see http://indiewebcamp.com/distributed-indieauth and http://spec.indieauth.com/ for more background). It is now possible for each person to delegate to an IndieAuth server of their choosing, rather than the relying site choosing which IndieAuth server to use. This makes it more resilient to failures.
Re 3: The cultural issue of associating your online identity with a URL rather than an email address has been the subject of much debate for a long time. I would also be open to suggestions on how to handle changing domain names, and whether that should happen at the IndieAuth layer or at the site you're logging in to. Feel free to add things to the wiki! http://indiewebcamp.com/indieauth
