Hey James,
Some time ago I started a series of widget helpers for jQuery - simple
but helpful helpers, that was the idea. :) And although i didn't had a
maxLength one, I would need one shortly and it was simple enough to
forge one for the collection, so here it is:

    http://dev.tipos.org/browser/trunk/Tipos/View/Helper/Jquery/TextLimiter.php

As said, it is simple: it takes the 'maxLength' attribute of a
textarea and apply it. To activate, this should be called in a view:

    $this->jquery()->textLimiter('#textarea_id');

And that's it.

One drawnback is that my jQuery helpers have some dependencies -
besides the base class and Helper_Jquery, I use my own version of
Helper_Js, which sets inline scripts using external observers instead
of an internal stack.

Anyway, the TextLimiter helper can give you an idea of how simple it
would be to implement one with jQuery. :)

cheers!
