register_callback & public-side admin plugins
I’m not clear on the purpose of public-side admin plugin functionality. Is this so that you can register callback functions that occur during the viewing of the site, such as textpattern()?
The reason I ask is I’m currently trying to compose a plugin that basically will auto_prepend itself to textpattern when a public page is loaded, so that it’s only executed once. For whatever reason, simply adding the plugin tag at the top of a page template appears to execute the plugin numerous times – but I can’t nail down what exactly is going on. Does textpattern() make several passes over the page template before outputting?

Currently, yes. You can use a static or global variable to prevent a function from being run twice.
You can also execute code at plugin load time, rather than using a tag.
