Good point. Yes, if the range of random numbers chosen is small. If the random numbers being exchanged are N bits long and the length of the hash is also N (say N = 256), then a salt should be unnecessary, right? Inverting an essentially random hash value should be impossible. But it's always possible that I'm missing something.
