With 128 bit keys collisions won't be your main concern, even with 64 bit keys
it takes a week, give or take, to average 1 collision, so we're probably talking
a few million years with 128 bit keys.

I consider it more likely that there is a bug in the move generator or that some
computer will overheat and produce wrong numbers, or there could be an error in
the transmission...

You can never be completely sure of that either until its been verified
independently.
