Here's how I solved it, using the technique @zzzzBov mentioned in his answer, to import zeroclipboard into the page via a bookmarklet.

When the bookmarket runs, a hand cursor appears on hovering over anywhere on the body. Clicking will copy (for example) the document's title to the clipboard.

(Links to zeroclipboard resources have been replaced with placeholders, and multi-line comments have been used since Chrome appears to be removing all line-breaks from bookmarklets (or something))

javascript:

var s = document.createElement('script');
s.setAttribute('src', 'http://example.com/ZeroClipboard.js');

s.onload = s.onreadystatechange = 
  function()
  { 
     ZeroClipboard.setMoviePath( 'http://example.com/ZeroClipboard.swf');
     var clip = new ZeroClipboard.Client();   
     
     /* glue to the body: sample only, in reality  we should
        probably create a new visible element and glue to that. */
     clip.glue(document.body);   
     
     clip.setHandCursor( true );
    
     /* copy to clipboard on mouse-up */
     clip.addEventListener('onMouseUp', 
      function (client) 
      {      
         /* example */
         var toCopy = document.title;        
         clip.setText(toCopy);    

         alert(toCopy + ' copied.');
         clip.hide();
      });  
   };

document.body.appendChild(s);
