Lineage and local actions

Is it possible to have local (portal) actions for lineage (the same way as lineage.registry /lineage.controlpanels ? )

Sorry, actions are still properties stored as CMF Action objects organized in CMFAction categories (folders) under portal_actions tool: No.

You might be able to emulate something like this with the "condition" property of actions -- provided lineage gives you the information for such conditions.
