Page Transclusion plugin?

I’ve got a couple paragraphs of text (with HTML and CSS) that I’d like to include on two pages of my site. This text gets updated on the order of once a month, so I’d rather not have to edit both pages to match each other all the time. If this were a wiki using MediaWiki, it’d be really easy to do that using transclusion.

Thing is, I can’t find any WordPress plugins that’ll allow me to do that with WordPress. I see a couple macro plugins, but neither lists support for WP 2.7, and text macros are generally much simpler than what I have in mind (and usually don’t need to be changed regularly). I also see a plugin that will transclude metadata for pages/posts, but not the pages/posts themselves.

Does anyone have the plugin I’m looking for? If not, might some enterprising plugin developer be interested in making it? It seems to be a pretty integral part of using WordPress. It also seems like it should be easy to do – I know I can do it by creating a custom page template with a custom single-post “loop” in it. That’s probably what I’ll end out doing, once I dig through the codex enough to figure out how to do it. But having something a bit more modular would be really helpful for sites that use WP as a CMS.
