I am really a fan of 1Password, especially due to it's multi platform ability (both in term of OS and browser). It really shine on MacOS, and the Windows version fulfill my needs when I am constrained to use it. But mobile versions are really less integrated and does shows the Agile touch!
Since I am a developer, I understand the difficulties you encounter, and I do not expect Apple to help really, but we need 1Password for iPad like it is on Mac, accessible from a full featured browser. Since Apple will be difficult to partner with, and you probably do not want to change your business in building the best browser ever for iPad, why not integrating with the many existing alternative browsers available from the AppStore ? Dolphin HD ? Diigo ? Knowtilus ? ... All of them?
For the editors of those browser, this integration could be a win-win operation.
