Perhaps I misunderstand your question, but AFAIK vocabulary support this 
scenario. In my application, I also have a country drop-down that is in my 
case filled from a relational database. The vocabulary looks like this:

def landVocabulary(obj):
    """Get ktoids and ktonrs from session"""
    session = zalchemy.getSession()
    laender = session.query(Land)
    laender_terms = []
    for n, land in enumerate(laender):
        laender_terms.append(vocabulary.SimpleVocabulary.\
                         createTerm(land.landid,
                                    n,
                                    land.name))
    return vocabulary.SimpleVocabulary(laender_terms)

# Make function a vocabulary factory
alsoProvides(landVocabulary, IVocabularyFactory)

and in my configuration:

    <utility
        component=".utils.landVocabulary"
        name="landVocabulary"
        />

Now I can use this vocabulary from any interface.

Best regards,
Hermann
