nice that there's another interested person!
The plugin is not really finished (as far as my wishes are concerned) - but it already works pretty good!
You can download it at here
This is a site of Wim Niemans who helped developing the plugin some steps further.
You can also see the glossary in action in that site (as usual its linked in the menu on top of each page).
We use it in our intranet knowledge site and have seen no problems so far.
Actual version is 0.9.4, but as usual that doesn't mean anything in open source software.
Please let me know if you downloaded and tested it.
There should be no problems *knock-on-wood*.
