1. There are no examples, this is green territory. 2. Again, it's new and up to you. Personally though, not sure I would bother. When an API does come out, it'll be different from yours and you'll need to re-do things. I'm also pretty sure that no end-users are going to want to install your custom ROM for some of this functionality. Unless you're just doing it for yourself or internal phones you control, this isn't worth developing to sell or distribute to 'regular' users.
3. Pretty much, though you might not need to install any app. You can just let it emulate the entire time and key off of that UID from the emulated tag. You can talk to it as if it were a MiFare card though if you don't do wired emulation mode. 4. No clue and Google isn't saying anything either.
