Janet Hawtin, one of the Linux Australia has put together an awesome document which poses questions and answers how the DMCA makes those actions unclear. Examples are being able to read your e-book aloud to your child, being able to install new hardware to your computer, and all kinds of scenarios that make is really obvious in a non-technical fashion why the DMCA style laws being enacted in the Australian/US FTA are so bad for us as a community.
Rock on Janet! Janet also did the Software Freedom Day posters and stuff last year which are all on her website so check them out too 🙂
