It’s a nice idea in theory – not having to carry bulky passports around and look after them while traveling in the bush.  CN Traveler’s article suggests that cloud based passports are the way of the future.  I would really love to be able to cut back on documents I have to carry, nothing worse than bulky neck pouches full of documents and wads of cash because credit cards are not widely accepted in certain countries – or at least the remote areas of these countries that eco-tourists get to.  I wonder how it works with countries like Brazil and Ghana where you still have to send your passport off to get the visas?   What about West Papua where you need a surat jalan to visit remote areas?  I’m all for anything that makes the red tape easier but I don’t think it’s going to happen in my travel lifetime!
