Can you clarify how one would lookup and call an action without it?  What
is the "id" of a component?  It's role?  It's sitemap hint?  It's fully
qualified classname?  I get the feeling it's none of these, or some
combination of these?

The migration path out of actions will be less painful if at first people
can easily call their action code from the flow (obvious to you I'm sure).
Understanding clearly how this is to be done will help me get a feel for
how painful this will be for non-insiders.
