I have the front brake on the right on all my bikes. Partly because I was a motorcycle rider, and partly because I wanted to have the strongest brake available if I were momentarily riding one-handed, for example when signalling. Maybe also, theoretically, if someone stole my bike they might get a little surprise! That's never happened.
As Cyccommute indicates above, this position is legal according to the CPSC if "a consumer specifies otherwise". When I bought my Airborne, the reversed lever position was an option; all my other bikes I switched myself.
