I'd like something like this with NFC support. I should be able to scan a tag, and the logs page for that tag just automatically pops up, and anyone else can also scan it and access the page, with full offline sync. Accounts could just be tags too. Hit "Write user credentials to card", tap a blank card, hand it to someone. Or you could do challenge response auth. Tapping the card gives you access to that note for some selectable time period, no accounts or settings, the tag is the note.
