Did you test it with virtual machine or real machine...? I myself haven't yet checked how HUD behaves in latest live builds, but if you tested using virtual machine, chances are that it wouldn't respond in a same way if Ubuntu got the keyboard input.
If Ubuntu is released with HUD like it showed in the beta build, all those Asian users must migrate to Xubuntu, Kubuntu, Lubuntu, or remove Unity and use GNOME. As a fan of Unity, I would really appreciate if the Design Team reconsiders the configuration, and only allow left ALT key to work as HUD shortcut. If users of European language feel more convenience when allowing right ALT to also work as HUD key, a configuration menu at the settings menu - I think - would do the job.
