Wow, that would be awesome. I didn't expect my little rant post to get a reply like that thanks.
EDIT:
If you perhaps did add that feature, you could add gamers to your target market and I think it would help quite a bit..
EDIT2:
If you really wanted to add gamers to your target market, add mouse sensitivity adjustment, screen brightness adjustment, bass boost gain adjustment, and xfi's 24bit crystalizer adjustment, all with working ingame display. If you did that, a lot of xfi users and gamers in general would probably love this thing.
