I didn't expect something that simple had escaped everyone's notice(though I suppose I should have said that more explicitly in my post) - I threw it out there because it made sense at first glance and had no immediately obvious problems, not because I figured I had definitely cracked the problem. Easier to see if there's a known response than to try to figure it out myself. So no, I'm not annoyed by your response.

And I do think I see what you're getting at. Oh well, it was worth a shot.
