Is there a possibility to save OpenACS from potential future trouble? (I don't want to make a big fuss about this topic, but it's always nicer to sleep quiet at night...)

I am thinking about the P2P File Sharing Systems, where users have to state that they are not sharing copyrighted files.

As soon as the OpenACS 4.x port is done with, contributers of new modules could state that they are not contributing copyrighted code. Is this reasonable?

NOTE: I don't want to offend anyone with this!!!
