Ubuntu is a Debian derivative, maybe like Debian it has built in handling for it.
I did yum search gnash and found it. so i installed it and restarted firefox but still that youtube page insisted i need a plugin that i do not have. looking more closely at the yum utput though there is a gnash-plugin... But youtube is being picky, it still insists I need an *Adobe* flash player.
According to http://fedoraproject.org/wiki/Flash gnash often cannot play sound because often sound in flash uses mp3, which is encumbered by patents.
The page did though show me that i should remove nspluginwrapper; presumably that is what keeps saying I need an adobe viewer.
Ok starting to see something, now some audio errors to deal with but looks like it might at least work for visuals and hopefully if people say anyt6hing worth hearing there will be transcripts to read.
It wants me to install gstreamer-ffmpeg but yum denies knowledge of any such package.
There don't actually seem to be any visuals either, apparently it is using some codec that also isn't available or isn't present or something, maybe the one that someone mentinoed earlier as not being available yet.

also running/installing flash on *nix is trivial...
