> Before we jump in, I wanted to share some history with you. Back in 2009 when we first built 1PasswordAnywhere, it wasn’t possible to use it with Dropbox. We couldn’t use Dropbox at the time because each file request needed to include a revision number and 1PasswordAnywhere had no way to know which revision numbers to use.
> Roustem and I explained this problem to the Dropbox Founder Arash, and he was kind enough to add a workaround to allow us to load files directly. This was state of the art technology in 2009.

If stores all the passwords in encrypted js files, which the 1password.html would read in and allow for totally offline password access.
