Apparently from the other posts my logic was appropriate for AC but not DC.

Personally I don't believe in the concept of zero resistance. That goes beyond reason. Nothing physical is *ever* zero (or infinite). But thats another topic.

BTW- just to continue our arguement purely for the sake of arguing:
Power dissipation in a wire of resistance R carrying current I is R*I^2.

True, but since I=V/R Power dissipation is also V^2/R. Does that mean it's independent of current too?

And this too..
If a part of the superconductor sees a greater voltage drop than the rest, as a result of an inhomogeneity, this part will heat up even faster

Voltage? Hmmm..
