[wp-hackers] Displaying a page on-the-fly with a plugin

[Dino Termini]

Hi everybody,

I'm developing a plugin that displays a page for the users with various 
options. Right now, I'm using

insert_post()

to create the page when the plugin is activated, and then 
add_filter('the_content') whose attached functions runs only if the ID 
of the current page matches the one of the page I created. Some of my 
users have pointed out that creating a new page 'clutters' their blog, 
so I was wondering if there's a different way to "load the current 
theme" and display my custom content in place of the_content(). Please 
let me know if you need more details.

Thanks,
Camu
