I think this a great idea for the wordpress track ~ I’m with @djpaul.. WordPress plugins should be able to declare a parent plug. I can declare that a piece of javascript has dependencies, or a theme, but not a plugin.. Are some of the more robust plugins (ecommerce, nextgen, etc) with sub plugins handling this? Someone should file an enhancement ticket.. this is very logical and would increase interest in child plugs, like those for BuddyPress.
