all plugins are included any time wp is loaded up -- it is up to the plugins 
to 'decide' whether or not to execute (i.e., I have some that turn 
themselves off when the page loading is under wp-admin/).

Process goes something like:

-> wp-config.php
-> wp-settings.php
-> setup wp caching stuff
-> twenty other files...
-> all plugins
-> setup query and rewrite objects
-> init main object, parse the request, send headers, run db query for 
-> template-loader.php

This is why when people ask if they should directly include WP in order to 
show recent entries on a home page or something, I tell them to use a 
caching feed-aggregator script, as including WP has a ton of overhead even 
if only looking at code loaded... ;)
