Even self-supporting run-flat tires have limitations when at "0" inflation - read the manufacturer's recommendations for the RFT you are inquiring about.

Yes it can, run flats are designed to get you to a garage or tyre place at slow speed and although they go down slowly once flat your running on rubber that will split due to the weight of the car, so any bumps, pot holes, might cause damage to the wheel.
Get a spare wheel kit, and put it in the spare wheel well

It certainly can, with no air in the tyre there is less shock absorption, so it goes straight to the rim.

Well as you can damage a wheel with the tire fully inflated, the answer would HAVE to be yes, you CAN cause wheel damage riding on a deflated RFT!

If your wheel has cracked then I would definitely replace rather then repair.
As for run flats cracking alloy wheels it has been a big problem here in the UK (with our third world maintained roads) and BMW have had a shed load of criticism and bad publicity from a BBC consumer programme over the issue. The very hard and stiff run flat tyre wall means the wheel will take the full hard impact of any pot hole or bump. Result a cracked or broken wheel.

According to my dealer here in Toronto, cracks in rims are a fairly common problem . I just have stock 17" rims without runflats and had to have a wheel replaced recently. Personally I think this is pretty pathetic for a $50K car.
