If you'd like to untether yourself and you don't have a fancy enough device to stream video while you're untethered, here are links to files containing the audio portion of the last three vids I've implored you to watch. Visit the download page for each and click the big blue "Download Now" button. (Whereupon you'll have to wait twenty seconds and then you'll get the actual MP3 link, which you can then right-click and save on. Sorry. Nothing is truly free.) If that fails, try here.
[Added] In Comments, Alastair points out a more direct option for the Moglen audio files. Thanks, Alastair.
The files are a little over 100 MB each. There's a torrent option on the respective download pages.
Let me know if you have any problems. Or successes, for that matter. Thanks.
