Hi Greg!

You can implement the ICustomPluginLoader interface on your plugin and in its implementaiton perform the needed checks
and return an empty array of PlugInDescriptor if your security checks doesnt validate, something like this:

    [GuiPlugIn( ... )]
    public partial class MyGuiPlugin : UserControlBase, ICustomPlugInLoader
    {
        public PlugInDescriptor[]  List()
        {
            if(!PrincipalInfo.HasAdminAccess)
            {
                return new PlugInDescriptor[0];
            }

            return new PlugInDescriptor[1]{ PlugInDescriptor.Load(typeof(MyGuiPlugin)) };
        }

        ...
    }
