Hi wesmip,
the legalities are outside my knowledge base but I think 'public domain' stuff would be a little risky. Might be a little paranoid, but I would err on the side of caution.
I, myself, would love to receive the fruits of your work and if you would (my email is DeeGee_88@Hotmail.com ) I would be most appreciative.

Good luck with your work and good punting,
Den
