jQuery - Pagination of Visible Results?

Hello,

I'm trying to paginate only visible results, after they have been filtered (made hidden or visible) by other jQuery controls. The plugins I have tried seem to ignore the filtering controls, by not updating the pagination after a filter has been applied or removed. How would I go about this? Printing a count of visible/total for the user would be a nice touch.

An unpaginated sample is available here. Many thanks to mplungjan, as this is the result of our Filter Results by More Than 2 Intersections discussion.

Any help is much appreciated.

Here is what I have so far. Not working at all but I really need to get away from the computer after 13 hours behind one

function onSelectCB() {}
function onFormatCB() {}


$(document).ready(function() {
    $('input:checkbox').attr('checked', 'checked');
    $(".chk").click(function() {
        $(".chk:checked").each(function() {
           $("."+this.id).show();
        });       
        $(".chk:not(:checked)").each(function() {
           $("."+this.id).hide();
           $("#content").empty();
           if ($(".courseBox:visible").length > 0) {
             $(".courseBox:visible").each(function() {
               var elem =$('<div>').attr("class","element").html($(this).html()); 
               $("#content").append(elem);      
             });
             $(".pagination").paging(1000, { // make 1000 elements navigatable
               format: '[< ncnnn! >]', // define how the navigation should look like
               perpage: 4, // show 4 elements per page
               lapping: 0, // don't overlap pages for the moment
               page: 1, // start at page, can also be "null" or negative
               onSelect: onSelectCB, // callback is called when user selects a page
               onFormat: onFormatCB // callback is called once for every "format" element
             });

I've taken several passes at altering the above code to achieve paginated display of visible elements, but so far no dice. Any further insight/input would be appreciated.
