              }
              // we should have included everything when we have come to this line,
              // so now delegate to the original jQuery ready check
              jQuery._super_ready(arguments);
          }
      });

It still needs some work (see the TODOs), but may be usefull nonetheless

http://docs.jquery.com/Ajax/jQ.....rlcallback

if (this.readyState == 'loaded' || this.readyState == 'complete')

I wrote similar plugin with working ondomready and dependency feauture:
http://meta20.net/.include_scr.....ery_plugin

Tested with jquery.forms. Hope you find it usefull.

Thanks
