Yes, I was thinking the same.

Linking a category to a list of categories... uhm.. not sure I understand...

Uh...You are talking about categories and terms as two different things. 
Why?  Aren't they the same?

I'm trying to grasp this... how should the autotagging be done? When the 
page get's displayed in the frontend (using a hook in the TSFE) or when 
a content element is created or updated (hook in tcemain)? Or perhaps by 
using a cron-job?

I'd also prefer if this could be implemented on a more general level - 
so that it will be possible to autotag records from arbitrary tables and 
define special rules and relations between them and other tables as in 
the case with pages->tt_content. This would make sense for tt_news and 
probably also other tables.

I'm thinking of something like this :

$TCA[tablename][ctrl][EXT][contagged]=array(
	allowAutoTagging => 1,	
	searchFields => title,description,keywords,blablabla,
	parentTables => tx_mytable,
);

(is this too esoteric?)

Again, I'm not sure I understand the difference between terms and 
categories.

Yep, so far only in the backend (using the Categories->List module) but 
I'm working on an API for FE-plugin developers.

My vision is a site with just one page and many categories. The first 
steps has been taken in EXT:categories/lib/class.tx_categories_menu.php
