    Any high level generic API must also have some chance of being
    implementable cross-platform, otherwise all applications will have to fork
    or the ongoing maintenance of the apps will have to stay with the LSM
    module producer. If what you want is to develop LSM modules why spend time
    maintaining apache ?
    
    
    I've argued in the past that a single binary application must also work on
    a vanilla linux distribution and a LSM system if LSM is ever going to be
    accepted by the general community. Not everyone agrees with that :-)
