Lee-
I'm not convinced. I generally dislike the idea of automatic content of any kind--the content of Wikipedia should be created by human editors, and even disambiguation pages should each be crafted uniquely to suit the needs of the subject, not just stamped out of a template.
I agree regarding the disambiguation pages themselves. In general, we should only use automatically generated/added content where it is at least equivalent to text written by humans. Using this criterion:
1) The "Alternate meanings:" solution by Magnus is a good one, because this is supposed to be a short line on individual articles that complements the longer disambiguation page. There is no point in having humans write and update this information, just as there is no point in having humans write the "What links here" information.
2) Text blocks that do not change are currently written for each inidividual page. On the main disambiguation pages, for en:, the following text block is currently used:
''This is a [[wikipedia:disambiguation|disambiguation]] page; that is, one that just points to other pages that might otherwise have the same name. If you followed a link here, you might want to go back and fix that link to point to the appropriate specific page.''
It may be useful to be able to transclude such text segments ([[>Wikipedia:Disambiguation]] or something like this). However, I am also thinking about having these segments be inserted as part of a general category scheme, such as
[[Category:Disambiguation page]]
Where that page would list all pages in that category, with automatic paging and sorting, and allow editors to define a standard block of text that is added at the bottom of all pages of that category. So we could use the same principle for
[[Category:Stub]]
or
[[Category:Deletion]]
To have texts like
''This aricle is a [[Wikipedia:stub article|stub]]. Please see [[:Category:Stub]] for a list of current stub articles.''
or
''This page has been marked for deletion. In order to debate its deletion, please use the discussion page.''
