First, I would like to thank you for your work on gnome-osd, I am currently using it for displaying Twitter messages (with users being able to post the messages for commenting the game) on top of football games of the euro08 in an Austrian pub, and it works fabulously.
Ha! Amazing and that my pet project of the past has been put to such a fun use :-) Strangely this makes me feel some kind of regret for not hacking GnomeOSD in a very long time. But I guess it's life... so much to do, so little time... :-/
