Hmmm. Broadcast royalties? If things have become that silly, then I'd argue that anyone listening to my music sent over my WEP secured 802.11b link is circumventing the copy protection and violating the DMCA or suchlike. If it doesn't matter legally whether or not copy protection or security works as advertised or is imperfect or is bypassable by trivial means, then the law cuts both ways and I can use the DMCA to argue I'm not broadcasting because I have put in place measures to stop unuthorised reception. Yep, IANAL!
