Making TSS Compatible with Profile_Taxonomy or User_Terms

Would anyone be able to point me in the direction of making TSS available with these modules?

http://drupal.org/project/profile_taxonomy
http://drupal.org/project/user_tags

Essentially my project requires users to sign up, check which topics they are interested in, using the same vocab as an article content type.

I could get Profile Taxonomy working with another module Project Checkboxes but it doesn't do the fieldset hierarchy grouping like TSS does.

Theres some additional discussion about these topics here:

Apologies if this isn't quite the right place for this discussion, its my first post in the community :)
