Searching jQuery Tooltip Plugin with AJAX support and easy integration

Right now I'm using a tooltip system based on overlib which looks good and works well. As I'm already using jQuery on my site I'd like to migrate to a jQuery plugin solution to reduce code an speed up usage. After searching for several hours I havn't found anything usable.

See here for the current implementation on my site (hover over WOFF on 2010-03-17 entry.

I'm looking for a tooltip which supports the following items:
  • Bubble style (kind of, should at least look fancy)
  • Positioning according to available space (display left/right/over/under link)
  • Content read via AJAX from single file containing all help texts
  • Easy integration into source
I would like to use links in a way like

This is a <a href="#_tooltipname">test</a>.

with one(!) xml or html file read by AJAX which consists all help texts. I would like to provide a kind of glossary for my site with certain words being explained by tooltips. It is possible that there are multiple identical words on one page thus no "id" may be used.

Any hints to a Tooltip plugin which supports this?

Thanks a lot for your answers in advance...
