An article found via Reuters talks about a bill in Connecticut and that there are several other bills working to become laws that will stop horny teens from getting the full charges of a child pornographer when they text nudie pictures to each other.
I have talked to shocked parents that find out their teenagers could be found guilty of child porn and have to register as a sex offender for the rest of their lives when their cell phone gets lost / stolen or found with pictures of girlfriends and boyfriends in the buff.
Several states are working on laws to fix that.
