This is the beauty of the Volt design. You don't need to deploy vast networks of chargers to quick charge. At some point, you have to ask the question, how much effort and money is it worth not to from time to time burn a gallon of gas. Leaf owners, when they ask me when I bother to lug around an engine I don't need very often get this reply: "because I'd rather haul around an inexpensive engine that gives me limitless range when I want it, than a battery pack that is twice as large as I need it to be and a lot more expensive that have limited range"
...

That all depends upon how often you need that extended range. If you need it once a decade, is it worth carrying around all that extra weight and displacing all that cargo/passanger space all the rest of the time? I would say not.
If you need that extended range twice a week? Yes, I would say it definately is purely from a convenience aspect (although one might also say sending just a little bit of money out of our economy and into the hands of our enemies is still too much).

If your driving patterns allow you to avoid the gas engine, you can easily use a skateboard design freeing up a TON of room for both passangers and cargo.

All that aside though, the drive free forever really isn't the case IF you want your car to last as long as possible. Quick charging the Model S is generally not recommended for longevity of the batteries. Doing it once in a while is no big deal, but doing it all the time, I would guess, could shorten the battery life.

I would like to see Tesla add, or allow other companies to add some L2 chargers to their supercharger areas.

Not to sound argumentative, but using the choices available to go out and purchase and take delivery as of the timestamp of this post there are the following options:
...

You have a 350 mile trip to take? You gonna do it in Telsa, you might not make the distance. Leaf? Not even close. Volt, prob can not only make it, but also have some gas left to create a few more electrons.

...When the day comes I can charge my car, get about 350-400 miles and charge it in 15-20 minutes and go another 350-400 miles, all electric is ready for the mainstream. Until then, we have what we have.

I agree with you completely, not argumentative at all. The Tesla, Leaf and Volt are all the best possible cars for people with the driving habits that each of those vehicles match.
You asked about what happens when you have a 350 mile trip. I would say you would drive your Volt by the sounds of it. For me, I NEVER have had, and don't ever expect to have a 350 mile trip. And the off chance I do, and have to drive myself, I will also take my Volt.
Each person buys the product that fits their needs. The Model S fits my needs perfectly. The Volt is a great backup in case I need to drive further, although if I get much further I would prefer to fly or take the train. I strongly suspect there is a sizable market share who's trips are within the limits of 265 miles. Time will tell.

My assumption is that this will be a benefit for early adopters. Basically, if you are one of the people who buy the first x1,000 Tesla S models, you will be given free access to the charge network. Anyone after that initial stage will have to pay for their usage.

I am curious how difficult it would be to make a J1772 adapter that would allow Volts to charge off that network. If the station were in a convenient location, it might be worth the time to stop.

Your assumption would be incorrect. Free supercharging is in effect for all 85kwh models.
Part of the reason it isn't even an option for the 40kwh Tesla's is it would fry that size battery pack or have to slow down to the point where you may as well be doing level 2 charging. And it that case why take up a spot when someone else can take advantage of the capabilities of the supercharger.

Tesla has something like a $600/year service fee. I think it ties in with maintaining the warranty. Nothing is free.

$475/year if you buy the service package. If you bump that to $600/year (both of these are 4 year contracts) you get unlimited 'ranger' service as well.
Both packages cover all consumables except for brakes/tires.
And no, you don't have to buy either service contract to maintain your warranty.
It is similar to any other car warrantee. You must have the vehicle properly taken car of. If you fail to put oil in a regular ICE for 3 years, warrantee won't cover it when it blows a rod
