Instead of categories I would like products to appear in the drop-down navigation menu similar to lowes.com. Is this possible? I am not paying for anything either :)

After a bit of experimenting I've got this working! Below is the new code to use in

app/code/core/Mage/Catalog/Block/Navigation.php

function _renderCategoryMenuItemHtml (swap 'local' for 'core' if localizing)

protected function _renderCategoryMenuItemHtml($category, $level = 0, $isLast = false, $isFirst = false, $isOutermost = false, $outermostItemClass = '', $childrenWrapClass = '', $noEventAttributes = false)
{
    if (!$category->getIsActive()) {
        return '';
    }
    $html = array();

    // get all children
    if (Mage::helper('catalog/category_flat')->isEnabled()) {
        $children = (array)$category->getChildrenNodes();
        $childrenCount = count($children);
    } else {
        $children = $category->getChildren();
        $childrenCount = $children->count();
    }
    $hasChildren = ($children && $childrenCount);

    // get products listing
    $cur_category = Mage::getModel('catalog/category')->load($category->getId());
    $_productCollection = Mage::getResourceModel('catalog/product_collection')->addCategoryFilter($cur_category)->setOrder('position','ASC');
    $k = 1;
    $hasProduct1 = $_productCollection->count();
    $phtmlChildren = '';
    if ($hasProduct1 >= 1) {
        $l = $level+1;
        foreach ($_productCollection as $_product) {
            $cur_product = Mage::getModel('catalog/product')->load($_product->getId());
            if ($cur_product->getStatus()) {
                $phtmlChildren .= '_getItemPosition($l);
                if ($k == $hasProduct1) {
                    $phtmlChildren .= ' last';
                }
                $phtmlChildren .= '">'."\n";
                $phtmlChildren .= ' '.$this->htmlEscape($cur_product->getName()).''."\n";
                $phtmlChildren .= '

';
                $k++;
            }
        }
    }

    // select active children
    $activeChildren = array();
    foreach ($children as $child) {
        if ($child->getIsActive()) {
            $activeChildren[] = $child;
        }
    }
    $activeChildrenCount = count($activeChildren);
    $hasActiveChildren = ($activeChildrenCount > 0);

    // prepare list item html classes
    $classes = array();
    $classes[] = 'level' . $level;
    $classes[] = 'nav-' . $this->_getItemPosition($level);
    if ($this->isCategoryActive($category)) {
        $classes[] = 'active';
    }
    $linkClass = '';
    if ($isOutermost && $outermostItemClass) {
        $classes[] = $outermostItemClass;
        $linkClass = ' class="'.$outermostItemClass.'"';
    }
    if ($isFirst) {
        $classes[] = 'first';
    }
    if ($isLast) {
        $classes[] = 'last';
    }
    if ($hasActiveChildren) {
        $classes[] = 'parent';
    }

    // prepare list item attributes
    $attributes = array();
    if (count($classes) > 0) {
        $attributes['class'] = implode(' ', $classes);
    }
    if ($hasActiveChildren && !$noEventAttributes) {
         $attributes['onmouseover'] = 'toggleMenu(this,1)';
         $attributes['onmouseout'] = 'toggleMenu(this,0)';
    }

    // assemble list item with attributes
    $htmlLi = ' $attrValue) {
        $htmlLi .= ' ' . $attrName . '="' . str_replace('"', '\"', $attrValue) . '"';
    }
    $htmlLi .= '>';
    $html[] = $htmlLi;

    $html[] = '';
    $html[] = '' . $this->escapeHtml($category->getName()) . '';
    $html[] = '';

    // render 'product' children
    $htmlChildren = '';
    if ($hasChildren) {
        $j = 0;
        foreach ($children as $child) {
            if ($child->getIsActive()) {
                $htmlChildren .= $this->_renderCategoryMenuItemHtml($child, $level + 1, $j++ >= $k);
            }
        }
    }
    if ((!empty($htmlChildren)) || (!empty($phtmlChildren))) {
        $html[] = ''."\n".$htmlChildren.$phtmlChildren.'';
    }

    // render children
    $htmlChildren = '';
    $j = 0;
    foreach ($activeChildren as $child) {
        $htmlChildren .= $this->_renderCategoryMenuItemHtml(
            $child,
            ($level + 1),
            ($j == $activeChildrenCount - 1),
            ($j == 0),
            false,
            $outermostItemClass,
            $childrenWrapClass,
            $noEventAttributes
        );
        $j++;
    }
    if (!empty($htmlChildren)) {
        if ($childrenWrapClass) {
            $html[] = '';
        }
        $html[] = '';
        $html[] = $htmlChildren;
        $html[] = '';
        if ($childrenWrapClass) {
            $html[] = '';
        }
    }

    $html[] = '';

    $html = implode("\n", $html);       
    return $html;
}

Basically there are two new added sections. The first section builds the product collection to get relevant info (name, url, etc). The second section appends the new unordered list inside the existing root category list items. Hope this helps someone. Now you don't need to pay $99 for the extension that is out there :)

Tested on v.1.6.1
