I think a better way to display dependency information is to have a prompt
that tells you which plugin depends on which. This prompt would only show up
when a user tries to activate or deactivate one or more plugins. This way,
we don't get three types of plugins.

You would have to be able to specify a minimum *version* of the master

True.

That would be super.  Question: what unique identifier would be used in the

Ideally, it would be the "Plugin Name" of the parent plugin. But given the
fact that versions would also be required, I think a function like
set_dependencies(__FILE__, array('Spam Karma' => 1.3, ...)) would be better.
