If i have the following harkup;

<div>
  <div>
    <div id='sameHeight'>One<br>two<br>three</div>
    <div id='sameHeight'>four</div>
    <div id='sameHeight'>five</div>        
  <div>
  <div>
    <div id='sameHeight'>four</div>
    <div id='sameHeight'>six</div>
    <div id='sameHeight'>seven<br>eight</div>
  <div>
</div>

How can I ensure that all divs marked as "sameHeight" are the same height as their counterparts in the other div?

I had a look at equalHeights plugin but that assumes all divs side by side are in the same parent. I need one that can either traverse parents or allow me to specify parents.

Is there such a thing or do I need to write it?
