Topic: how to load a plugin on the run?

Hey all,
I have a multisite app and I want to load certain plugins for each of them. Is there a way to use a before_filter that would load a given plugin by looking at the url? If so how?

thanx in advance

Are these just standard vendor/plugins/? plugins?

they are plugins that override some of the controllers or models of my application. is there a way to load them all and then ignore some of them given a particuliar url?
