Marcos, I'm curious to learn where the requirement that "Must not allow addressing resources outside a widget" came from? Can you point to a precedent for such a restriction in any other protocol? I remember TimBL writing something to the effect of "Anywhere you can use a URI, you can use any URI", possibly in his design issues, but I can't find a reference right now.
I also don't understand what that bit about "run on the web" means in the intro. Thanks. Mark.
