I'm interested in the RTMP video over http protocol because I'm interested in video streaming. From reading the wikipedia entry, I saw that Adobe published the RTMP spec. Surprisingly, it had a license accompanying it - I'm not used to seeing a license next to a specification, so I read the license rather than downloading the spec. Shockingly, the license contains this statement:
Prohibited UsesThe rights and licenses granted by Adobe in the RTMP Specification, including those granted inthe Patent License, are conditioned upon Your agreement to use the RTMP Specification for onlystreaming video, audio and/or data content and not to make, have made, use, sell, offer to sell,import or distribute: (i) any technology that intercepts streaming video, audio and/or datacontent for storage in any device or medium; or (ii) any technology that circumventstechnological measures for the protection of audio, video and/or data content, including any ofAdobe’s secure RTMP measures.
