Subscribing to specific content type by taxonomy term/tag OR Vocabulary

Hi,

I am wondering if Service module can assist with getting the Notifications module to allow users to subscribe to specific content types by taxonomy terms/vocabulary. i.e. Content Type - workshops AND Taxonomy Term - life drawing.... OR Content Type - workshops AND Vocabulary - Art. What is needed is to tie the subscribed content type to a taxomony term/vocabulary to focus the search. A person may subscribe to multiple content types under the same terms.

Thanks in advance!
