Thanks to the great suggestions both here and in #rails-contrib, I'm working on a slightly different angle to this patch. Hopefully I'll have the code finished in another day or two to post up here for review, but hopefully I can address

There's actually a somewhat major issue with this patch, with respect
to multi-model forms.

Because the elements are submitted as an array [{}, {}, {}], they are
completely incompatible with ajax submissions of forms. When rails
receives params in an array format (param[]), it reads each element in
the order it receives it, until it reaches a duplicate key, that's
when it decides to create a new element in the array that your
controller ultimately sees. When forms are submitted via ajax, it
isn't really feasible to make sure that elements are submitted in
order. This is partly why I wrote attribute_fu, even when Ryan Bates'
solution was wrapped up in the multi-model forms plugin.

The hash that a_f generates is ugly, but it works in all cases. This
patch, unless amended to support those ugly hashes instead, is going
to cause people a lot of headache when they can't figure out why their
ajax forms won't save right. Or worse, when the attributes are all
getting crossed up between the different elements.

Sorry for a little off-topic but does anyone of know how to support an

object that inherits all attributes through STI when I
use :accessible=>true?

For example:

Object A belongs_to object B and B has_many A objects.
Object B is accessible for A.
Objects C and D inherit their fields through STI from the B object.

I want to create a form that will allow me to fill object's A fields
along with C or D's fields.
The form should have a type selector so that user can choose if he
wants to fill a C object or D.

Form has:
- object A fields
- choose object type list

a specific B inheriting object (C or D)

- depending on the type selected in the list above a set of fields for
