Find small independent bands and movie directors/producers that share their stuff via torrents, and start seeding. Or find these people and ASK them if you can seed their stuff for free, over P2P networks. Make sure you get that in writing, though, the bit about them wanting you to seed the stuff.
Not sure what your plan is (surely, you must be a lawyer?), but I don't believe a non-copyright holder can take you to court over someone else's copyright. See the Righthaven case for more info.
