Refresh loop of custom posts (div) after new post is published

Question

GOAL Wondering if following should be done, I would like to (ajax?) refresh not necessary only (custom) post type loop or div

example custom post query :

<div class="refreshed posts">
<?php

global $post;

$myposts = get_posts('post_type=employer&numberposts=5&orderby=modified&offset=0');

foreach($myposts as $post) :

setup_postdata($post);

?>
</div>

CONCLUSION

Auto refresh posts can help my website users to see that when for example somebody submits a post type employer entry, at the same moment all online users can see all updated "employer" posts including that one submitted post. I would like to avoid using plugins. In the similar manner uses facebook etc their notifications (I believe they scheduled to refresh in minute intervals)

Answer 1

With the Wordpress 3.6 heartbit Api this should be easier.

With previous Wordpress version you have to play with ajax and js setInterval() function.

Edit

@Daniel Foltynek suggest this plugin.
