Will the Prism OnDemand module load in OOB mode?

Should loading OnDemand Prism modules work in an OOB environment? If so, I cannot get it to work. Everything currently works in the browser without any problems. In particular, I: register my modules in code:

    protected override IModuleCatalog GetModuleCatalog() {
        var catalog = new ModuleCatalog();
        Uri source;

        if( Application.Current.IsRunningOutOfBrowser ) {
            source = IsolatedStorageSettings.ApplicationSettings[SOURCEURI] as Uri;
        }
        else {
            var src = Application.Current.Host.Source.ToString();
            src = src.Substring( 0, src.LastIndexOf( '/' ) + 1 );
            source = new Uri( src );
            IsolatedStorageSettings.ApplicationSettings[SOURCEURI] = source;
            IsolatedStorageSettings.ApplicationSettings.Save();
        }

        if( source != null ) {
            var mod2 = new ModuleInfo { InitializationMode = InitializationMode.OnDemand,
                          ModuleName = ModuleNames.mod2,
                          ModuleType = "mod2.Module, mod2.Directory, '1.0.0.0', Culture=neutral, PublicKeyToken=null" ),
                          Ref = ( new Uri( source, "mod2.xap" )).AbsoluteUri };

            catalog.AddModule( mod2 );
        }

// per Jeremy Likeness - did not help.
        Application.Current.RootVisual = new Grid();

        return ( catalog );
    }

later request for loadable module:

mModuleManager.LoadModule( ModuleNames.mod2 );

and wait for the response to the event published during the initialization of this loaded module.

The module never loads, and when the application is running under the debugger, a message box appears saying that the web server returned a "not found" error. I can take the requesting url for the module and enter it in Firefox and load the module without problems.
