Bill S. recently started a thread about detecting whether you are in a gravitational pull or being accelerated by a rocket. I have just started re-reading "Black Holes and Time Warps" by Kip Thorne. He pretty much answered Bill's questions in the second or third chapter when he discusses Einstein's theories. The answer is that Einstein's thought experiment assumed a very small reference frame so that you could ignore the effects. It's a good book, I recommend it. It isn't the newest, but most of the first part of it should still be relevant.

C is the universal speed limit.
