Generally if a CV joint goes the worst problem would be a LOUD clicking sound from the axle, especially on turns. If it were to SNAP (which it really can't do, but I guess it COULD fall apart) it would just leave the wheel freewheeling.
I snapped the outer joint on my tercel. Grenaded is more like it. I decided to try a neutral drop from redline while showing off. Whoops. It was about $100 for another half shaft. Generaly, when a joint starts to go, you will hear a clicking when turning. At that point, it is time to get a new one, and send your old one back as core while it is still rebuildable. You can get a split boot to repair it, but they are a PITA to do. Just get a reman one.

If the CV joint by the wheel does go, that end of the driveshaft could fall out and do damage, depending on the type of inner CV joint used (tripod vs. ball bearing). Most use a tripod style inner joint that allows the shaft to move in and out.
That is true. the innner joint takes up the in and out, and up and down play, while the outer does the turning and the rest of the up and down. because of the turning, outers tend to go first. As for the shaft coming out, it can, but only if the half shaft breaks. if you just grenade the outer one (like I did) then it will stay in the car, contained by the hub system, and usually the outer race (unless you REALLY toasted that joint)

Actually, the car will not go at all, unless there is a limited slip differential (almost no FWD cars have one). Of course, if it did have a LSD, and you tried to drive it, the LSD wouldn't work for long because you would burn it out quick!
Actually, in either case the car will not go at all. in an open diff, the wheel with the least amount of traction will get the power. A LSD (limited slip differential) transmits to both. but most requre a force of some kind to be on both sides. the LSD has to ramp up, and to do that, some force from both wheels is required. If the joint goes, then that wheel is transmitting no force whatsoever to the LSD. A locker is different than an LSD, and physicly locks the axles together, so it is possible to drive with only one half shaft in a locker equiped vehicle.

You are right, if the brake job is done on an UNBROKEN axle is completed, it wont come out. But if the caliper was removed on an axle in a solid axle design that was snapped, there would be noting to stop the axle from sliding out. However, the caliper will hold the axle in.
Can you explain why a caliper would NOT hold a broken shaft in?
The axles in some vehicles are held into the diff with a "c" clip. If that C clip breaks, the axle will slide right out of the axle tube. The only thing that would be holding it into the vehicle in that case would be the caliper and rotor. Since the axle tube is usually not large enough to let the axle fall enough for the rotor to come out of the caliper (if the axle snapped at the splines), the axle should stay put. but as above, you will stop without a locker in the diff. If you drive like that (IF you can drive like that) you will distroy the axle, tube, rotor, caliper, and just about everything else
But the vast majority of the vehicles with those axles are drum brakes. In that case, watch as your axle and wheel pass you on the road.

What domestic muscle car in the 1960's had a rear transaxle, yet was a front engine car? (hint: it was a GM)
The polaris. but I didn't think it was ever produced.
