First question does AmigaOS have Python v2.0 or above?
QuickTime has a YT uploader built-in and I think this is pretty cool having used it myself in the past.
It would be a real boost if we could see this integrated into MPlayer, DVPlayer or any other third-party application.
Select a video to upload off your hard drive, window opens, enter username and password. Authentication starts, if passed, video begins to upload to YT.
