From IT Conversations is the Podcasting Legal Guide
Blurb:
Podcasters may unexpectedly find themselves on the wrong side of the law. Copyrights, attribution, fair use, inducement, defamation and privacy are just a few of the issues which must be finessed to avoid ending up in hot water. Luckily, Colette Vogele and her colleagues have published an excellent, free guide for podcasters on their legal rights and responsibilities. Denise Howell sits down with Vogele to discuss this ‘participatory law’ project which helps demystify the legal dangers raised by the blossoming of audio and video podcasting.
This would apply to the US mainly but I’m sure Bernie Goldbach of Digital Rights Ireland would have a lot in his podcasts that cover this particular issue too.
