Will and I already sketched this out here, it is just that neither of us has been sufficiently motivated to hack a Mediaiwiki plugin to present things the way we want.
Basically, we want to put the glossary tags into the full wikicha articles as metadata, and have the Glossary page index them into tables automatically in the format I demonstrated. One would also want permission from Lew to start with his already extensive glossary of terms.
PHP coders, start your engines.
(Partial credit for a backend type script that parses the data from the full articles and compiles an index in wiki format to be posted manually. This could be done in pretty much any language you like.)
