I have no problems with skip shift. I know a lot of people that really don't have a problem with it - and those that do get a CAGS eliminator. Easy as pie.
On terms of a manual switch, I do not know about that. If there was such a switch, it would likely be integrated into the traction/transmission/stability switch, simply engaging or disengaging when the driver wanted "sport". But at that point, you're going outside the CAGS range anyway, so it would be unnecessary to have a switch.
I'm more curious what happens if you drive a car with it and test the EPA rating and then disable it and test it again.

I don't really think such a change is necessary. I don't see how drain down and dry parts will be a result of sitting at a light with the ignition off.
With the latest EPA ruling on CO2 and the face off regarding Cap and Trade which will likely ensue, lots of measures regarding emissions will be institued, IMO.

* Oil pump primes the system to 60psi while the fuel pumps are priming before initial starting, so you greatly reduce wear during the initial cold starts - for the life of the car.
* You gain back the parasitic losses that the mechanical pump takes away from the engine - just like racers and tuners using electric fans and electric water pumps. Every 5hp counts.
* Easier to track and adjust pressures to suit the engine/speed/need
* Potentially far easier to change or service - especially if it's external as it should be.
* DO the words "dry sump" mean anything to anyone...
You can go on and on.

When automatic transmissions have a sport mode, then I believe EPA makes the mfr do two runs and take some sort of average, do they not? Maybe Ford will negotiate something similar here.

From what I understand, the shifting strategy in the EPA cycles assumes a robot shifting at fixed speeds, and that's why skip shift works so well. Of course, that's not the way I (or most other people, I think) drive a manual. I tend to shift as soon as I can without lugging. So for me, skip shift is a loser, as it requires I rev the car higher in 1st gear.

So I just got finished arguing with a Ford buddy of mine about the Skip Shift. It was a intresting arguement and I feel it'll probobly come up again so I just wanted to know if any of you have some facts.
My buddy claimed that the upcoming 5.0 Mustang WILL have Skip Shift, since it will be just shy of Gas Guzzler standards. However he told me something intresting he claimed it will have a On & Off button similar to a traction controll on/off button on a car. SAE claimed that as long as the car starts with the skip shift on, it can give them higher gas mileage rating. Even though the driver can turn it off.
Now, I'm not absolutly postive, but I think if thats true, the new 5.0 Mustang will be the first Ford with Skip Shift. GM has used the application in a couple of vehicles in the past 5 years. So I was wondering, is there any chance GM will go this route, I think the on / off button would save alot of complaining from people who don't know about the skip shift until after they get the car.

1. The 5.0 Mustang isn't using skip/shift to avoid Gas Guzzler. Like you mention, it's using it to boost fuel economy.... it be notably higher than the current 4.6 despite having at least 80 more horsepower.
2. I can easily see Ford adding a bypass feature (button or otherwise), being that Ford pretty much takes the pulse of the Mustang community and all but runs everything they plan to do (or not do... ie: live axle) through them.
Trivia: the 4th gen used skip-shift to pass driveby noise standards.
