Dynamic/ajax updated fields

[Rayken]

Is there an option for fields to update based on another fields value? I'm not talking about showing or hiding fields based on conditions, I'm talking about populating fields based on other field values. Is there some way we can attach ajax handlers to fields with a callback?

Ideally I'd want to use one field to control the options of another one, dynamically.
