This seems the best place to post this, but if I've misjudged that please move it (if you're a moderator) or let me know.

We're using User Defined Forms and the Taxonomy module. We want to integrate the two. Specifically, we want content editors to be able to select any existing taxonomy instead of manually entering options for drop-down lists, checkbox lists or radio button lists. There are two business requirement that make this tricky:

• the options must be included dynamically, not saved in the EditableOption table
• we can't fork and edit either module - we'll have to use extensions or derive replacement classes

Has anyone done something similar? All input is welcome.
