But we're still speculating, the fact is we just don't know exactly how it'll all work out. When people ask specific questions about detailed situations, they are unanswerable at this stage of the game. Even after it's signed into law, it's only Congress's framework of intent. The various agencies that create specific rules of implementation is where the questions get answered... and the courts.
I don't think it will ever be repealed, but I'm sure we will see a lot of massaging, in the future, to iron out snags/unintended consequences, expand/contract coverage, and adjust for budgets.
edit:
There was a story about Switzerland on TV today. They addressed universal coverage by requiring everyone to buy health insurance, everyone. It turned out to be much more expensive than they had planed. In the range of 10 to 11 % of GNP, as opposed to the US's 15 to 16 %. But they do have the Rollex of health care systems.
