[wp-hackers] is it possible to change the_title halfway into the processing of a page/post?

Yes you are right; and that is the criteria I use for choosing whether code
should go in functions.php or a plugin: "If I want to change themes, will
it break?"

So in this case the answer is "yes", so you need to put that code in a
plugin:

The template_redirect hook,
And the db access and display functions.
Add a hook for wp_title
add a hook for the_title
add a hook for 'the_content', that calls your display functions.
That way, any theme that calls the_content on your page will be get your
display output.

It was quicker to knock up an example than to explain the details. See

Hope that helps.
