How to manage auto complete HABTM in Rails?

Question

I am looking for a good solution to a typical model management problem with the HABTM association in Rails.

Suppose we have two models - products and categories:

Products
  has_many :categorizations
  has_many :categories, :through => :categorizations
Categories
  has_many :categorizations
  has_many :products, :through => :categorizations
Categorization
  belongs_to :product
  belongs_to :category

Pat Shaughnessy is developing a modified auto_complete plugin that allows you to manage a one-to-many association (and many-to-many):
