    //nugget: what i read was that the WindowsIdentity info is based on security tokens and the tokens are cached _ONLY_ at login time and is absolutely *not*refreshable* in any way other than logging out and back in
    //nugget: (e.g. WindowsIdentity.GetCurrent().Groups)
    //(from grp in WindowsIdentity.GetCurrent().Groups
    // where grp.Translate(typeof(NTAccount)).Value.ToLower().Contains("iTRAAC_Users".ToLower())
    // select 1).Count();

    //nugget: especially under the oppresive yoke of Vista, it is prohibitively annoying to force a user log out/in at applicaiton install time
    //nugget: and it's easily forgotten to do this up front
    //nugget: so ideally we support the scenario of launching CompMgmt.msc under temporary admin credentials and adding the user to this group on the fly
