    XML Secure Data Service

    Hello,

    I'm trying to figure out what would be the best technology to work
    with in terms of network connection and services to do the following:

    - I want to build a Window based application for internal use only.
    - The application needs to access data 'somewhere' in a secure way,
    with different access levels / credentials.
    - The application needs to send some other data to the central place
    as well.
    - The application needs to work offline using the data it will have
    downloaded.
    - The Data will be XML so it can easily be converted into Word or PDF
    documents and EXCEL reports.
    - The Data is edited only by selected users, most users will only use
    the data in read only, but send other type of data back to track how
    it was used.

    In terms of network access, I am wondering what would be best; public
    web server would require pretty good login security to avoid being
    hacked.

    I'm thinking about using access to an intranet through VPN, with a
    login process checking credential and filtering the DB with XSL
    through something like a CGI or PHP script, and send over only the
    parts of the DB the user needs, and store it on the local machine for
    offline access.

    For the interface, I'm using C#.

    Any better idea? or suggestion?

    I am also thinking about mobile phone access: I have no idea if cell
    phones are able to use VPN access. Anybody know?

    Thanks for your suggestions.
