That's possible, but you'll have to take care of passing the right
context everytime:
//main page
<script type="text/javascript" src="jquery.js"></script>
//inside the iframe
<script>
$ = jQuery = $('iframe')[0].parent.jQuery;
$('#myElement', document); //pass the iframe's document as context
</script>
to exemplify, if you were to do this "from the outside":
//main page
var iframe = $('iframe')[0];
iframe.contentWindow.$ = iframe.contentWindow.jQuery = jQuery;
iframe.contentWindow.$('.iframe_element', iframe.contentDocument);
//jquery will search in the context of the document it was loaded in,
if you don't specify one
the practical way to do that would be to save the iframe's document in
an object and always start from there:
var $iframe = $( $('iframe')[0].contentDocument );
$iframe.find('#iframe_element');
$iframe.find('.another_element');
There are probably other caveats for this use of jQuery, it depends on
the complexity of what you're doing.
