 I of course tried '''exactly that''' first (see long boring story above).
 Like so:

 {{{

 /* included minified jQuery */

 var mypluginjq = jQuery.noConflict();

 /* included minified jQuery UI */
 /* included minified Iris */

 mypluginjq(document).ready(function($) {

     /* My Plugin jQuery stuff */

 });

 }}}

 As instructed here:
 http://docs.jquery.com/Using_jQuery_with_Other_Libraries
 and here:
 http://docs.jquery.com/Core/jQuery.noConflict

 ''It did not work.'' When I called a jQuery version check outside and
 within the scoped functions it reported the same version everywhere - the
 last one loaded. And when called from other plugins, all reported the same
 version of jQuery, the last one loaded.

 The difference being perhaps that I am mostly trying to use fully scoped
 jQuery UI themes and I see detail here that most do not or perhaps never
 will.

 My guess is that no one has ever tested enough functionality to see a
 difference. Or actually made version calls.

 Maybe I screwed something up, but I don't think so. I'll try a very simple
 test page to see...
