Okay, this is coming from left field, but this thread plus another thread where a guy talked about running 100% ethanol got me thinking. For the guys running boosted engines and really pushing it, would it be advantageous to have complete control over how much ethanol is mixed and when? If you completely isolated the PI and DI systems; separate tanks, pumps, and lines, you could fill the PI with 100% ethanol, and using these tables have precise control over how much ethanol you are adding to the fuel. This would theoretically give you the ability to really fine tune the system for engines pushing the envelope. Gasoline burns with more energy, but the ethanol raises effective octane. I find myself doubting it would be worth the trouble, but it is a somewhat interesting thought experiment.
