We are already doing this manually, although only with 2 computers (if
the residues match, you don't need the 3rd one). We're taking residues
every one million iterations, and mail them to each other. So far, they've
matched :-)

And if one machine is faster than the other -- well, then it goes on to
another exponent. No waiting needed.
