dynamic font resizing in menu bar

[howie2009]

Hi Guys,
I have a multi language cms site and need to be able to resize font to fit the div its contained in so eg if I have a 300px wide navbar with 13px text:

home | about | contact | services | products

and in Russian its:

fgfgdg |gghgfdhggghgfhgfh | gfg |gfdgfgdfgfdgffd dgfdgdg | gdfgfgdfgfgdfg

I would like the font size to reduce down to fit the 300px fixed width div from say 13px to 10px or whatever fits.

so it would be like:

fgfgdg |gghgfdhggghgfhgfh | gfg |gfdgfgdfgfdgffd dgfdgdg | gdfgfgdfgfgdfg

I was looking at http://jsfiddle.net/e8B9j/2/show/ and was hoping someone could get it to work to suit the above. So as above u'd have say 5 menu item divs nested in a navbar div

<div id="navbar">

<div class="menuItem">item</div>
<div class="menuItem">item</div>
<div class="menuItem">item</div>
<div class="menuItem">item</div>
<div class="menuItem">item</div>
</div>

...or using ul and li's

Any help greatly appreciated. Perhaps a jquery solution out there?
Thanks
