How would you write the traditional elemental planes into Eberron?

In Eberron is it feasible in the world to have a one or two man airship?

We really are looking at ways to bring all the settings back

Does all (arcane, divine, natural, etc) magic rely on the Weave?

Do any entities hold jurisdiction over the various waters and coasts of Eberron?
