Late to the party, but I found guillaume06's solution worked well, and I added some additional functionality to it:

What this will enable: You will be able to specify the tag owner by the name of the relationship between the tagged model and the tag owner model.

How: write a module and include in your lib on initialization (require 'lib/path/to/tagger'):

  module Giga::Tagger
    extend ActiveSupport::Concern
    included do
      def self.tagger owner
        before_save :set_tag_owner
        def set_tag_owner
          self.tag_types.each do |tag|
            tag_type = tag.to_s
            # Set the owner of some tags based on the current tag_list
            set_owner_tag_list_on(owner, :"#{tag_type}", self.send(:"#{tag_type.chop}_list"))
            # Clear the list so we don't get duplicate taggings
            self.send(:"#{tag_type.chop}_list=",nil)
          end
        end

      end
    end
  end

Usage Instructions:

  Given: A model, Post, that is taggable
         A model, User, that is the tag owner
         A post is owned by the user through a relationship called :owner
  Then add to Post.rb:
         include Tagger
         acts_as_taggable_on :skills, :interests, :tags
         tagger :owner
  Make sure Post.rb already has called acts_as_taggable_on, and that User.rb has acts_as_tagger
  Note: This supports multiple tag contexts, not just tags (eg skills, interests)..
