As far as I know, that isn't exactly true.  Yes XVideo and XVEnc are
available, but there are no UNIX apps that use the XVEnc API at this point.
Windows multimedia redirection is just using XVEnc to send video to be
decoded on the DTU.  UNIX apps are using either XVideo or normal display
updating, not XVEnc.  Flash on UNIX isn't even using XVideo but because the
Sun Ray protocol itself is already pretty efficient, you may get pretty
decent results anyways.  But if you compare the bandwidth usage of Flash on
UNIX and Flash on Windows with MMR, you'll notice the former is much higher
because it isn't decoding on the DTU, it's just sending frames.  In that
way, the Sun Ray firmware doesn't have to be updated for Flash 10, as long
as the browser plugin works, the Sun Ray will be able to show it too.
