I think the answer is very clear for the next two or three years:

Qt must compile in either way and must provide THE SAME ABI. That is, if you 
enable C++0x, it should not create any extra symbols. And if you don't compile 
that, then you can still use C++0x features in your code, along with Qt.

We've so far been able to do that. The only thing I have tried so far and 
haven't been able to keep completely inline is move constructors for classes 
with non-inline Privates. I also expect that we'll be unable to use rvalue-
this for non-inline classes.
