Recently at a relative’s party, I noticed in the finished basement a wall-mounted area heater that runs on natural gas was being fed by a 30-foot run of flexible yellow gas pipe. This is not the stuff used on dryers or stoves, it has a smooth plastic yellow jacket, stainless steel liner, and is just over 1" O.D. The rest of the house has standard black pipe for all gas runs. Some questions:
1. I heard it is very new, and you must be "schooled" on it to install it. The installation is in Illinois. I've never seen it at big orange or Lowes.
Does it have a trade name?
2. PRO: Long runs, no joints to worry about . CON: Would appear to be easy to accidentally put a nail through it. Is this stuff legal in Ill? If not, where?
3. Ok, there is no third question, except that obviously I'm clueless on this, and if I ever run into it on an inspection I would have to do some fast research and ammend the report later, which I don't want to do. My insticts tell me it's not as safe as black pipe. My brain is telling me I'm missing some new product that saves time and money and is safe, since there are no joints to worry about. What's the scoop? I'll try to get a photo if that would help. Thanks for any comments!

Easy to install and simple to run without all the elbows and “t’s”. The only downfall that I can see is that you have to build everything from the manifold, if that really is a down side.
I believe it is better, at least I find fewer leaks in this stuff than the pipes with all those stinking fittings.

Yep,
Used here in new construction and upgraded gas installations.
This piping has no limits. Black metal piping had minimum limitations as to how far away from shut-offs this could extend.
This line has much higher limitations. This flexible piping saves installers 1/2 the time for installation, which is passed on to homeowner savings. Like Joe said "no tees or elbows have to be installed". This alleviates the tap & die process, and that lessens the chances of future gas leaks. This piping is going to work great in earthquake country (very flexible).
I'm starting to see these long yellow hoses more frequently.

Passing through walls / floors - yes. This is made for that use.
Passing into a furnace - I am going to say no because you need to have a cut-off valve before the furnace, thus the jacketed gas line would end at the gas cut-off valve, then the cut-off valve, then the sediment trap, then a gas connector going into the furnace.

I just ran into this myself.
My Mom wanted her thermostat moved in her new house, I go up into the crawl space and find what appeared at first to be plastic gas line I was very surprised. 
After a closer look I saw metal, but to those of us used to black iron it was a surprise.
I had to ask a plumber friend about it for some reassurance that Mom was not about to blow up.

Yes I have observed Yellow gas pipe showing up all over my area wished it had been available years ago. I have observed numerous furnaces connected with this piping and they do stop just to the exterior of the of the shut off valve and dirty leg on the furnace. But I am sure over time we will see some jake leg take the flex line inside the furnace cabinet but that is what they have us for.

BTW: Its called corrugated stainless steel tubing (CSST). It is very good stuff, but there are a lot of manufacturer’s specs that address the installation that a person should be aware of.

And one brand used a lot here is Trac Pipe. I have their manual. On the first page it states that their pipe may only be installed by installers trained and certified to install their pipe.
They are specific minimum radius bends (which are rarely followed) and the strapping is rarely followed (much less use the correct type straps).
For "certified" installers, they sure do not know what they are required to do. Either that, or they "know it" but just do not do it.
