There seems to be a great need for an Open Source password vault codebase/library that:

    Runs securely cross-platform, including tablets & smartphones
    Can present a great looking UI across all platforms
    Has no licensing issues in proprietary walled gardens
    Can securely support plugins to integrate with webapps

This would enable startups in the personal security space to be able to serve user's needs for tracking their credentials without creating a high value centralized store of sensitive information.
