Seth's post is a little vague, so here's a specific scenario: If a video is available only as an RTMPE stream, then the only way to capture a lossless copy of that video for fair use purposes is to write an unauthorized RTMPE client (ripper), which would probably violate the DMCA and get smacked down by Adobe immediately. Also, open-source Flash players probably won't be able to play RTMPE streams at all, for the same reason.<p>Adobe is planning to add even more DRM in AIR: <a href="http://www.flashcomguru.com/index.cfm/2007/10/23/Flash-Video-DRM-Roundup" rel="nofollow">http://www.flashcomguru.com/index.cfm/2007/10/23/Flash-Video...</a>
Adding DRM to Flash will lock out open and interoperable players. However, when Flash is used to play video, Flash itself is used as a crude form of DRM. This creates a "look but don't save" environment to which most people are already accustomed.
