Hey, I adapted the AddressField handler code to work with the Fivestar Module field. The upside and downside is it automatically fills out the voting api table. The INC file is attached to the post as a txt.
I see you've submitted this to the fivestar issue queue, which is the best place for it.
The best way to get your submitted changes reviewed is to submit a patch.
