Right, not until April 2010.

Is it *just* youtube videos that's causing the problem?  If so, you can try
something that I've been recommending to people:

1) Install greasemonkey (it's in the repos)
2) Install the hqtube greasemonkey script:


There is a minor bugfix needed in the discussion forum for the script.

What this script does is substitute a gstreamer totem window for the flash
plugin on youtube.  Other flash sites (say some games or the like) will still
use flash.

Or, alternatively, I've had good luck with viewing flash videos using gnash.
However, installing the gnash plugin will make it so that ALL flash apps go
through gnash.  Testing would be required to make sure that it works for all
your use cases.

One of the things that I recently commented on in the #ltsp irc channel is,
when ltsp4.2 came out, flash was a luxury that most teachers didn't want,
simply because they didn't want kids fooling around.

Now, a scant 5 years later, it appears to be pretty much manditory.  Until
either Adobe makes it's app more "multiuser" friendly, or flawless Free
SOftware alternatives come to the fore, yes, we're back in the hardware arms
