the fogg bags were my first thought but the everyday messenger from kickstarter really might be the right answer.
I agree that bag looks to be quite the nice piece. As a "one bag to rule them all", it looks both small and large enough to handle everything, and adaptable enough to do the number.
But it's hard to say what it's like to wear and use until you see one in the flesh...
