Hmm. How about this for the OP. I believe the new 2.3 rng has a
period many bits longer than 2^32. So start with a seed for machine
one. Generate, say, 1 billion pseudo rns. That is the starting key
for machine two. Repeat for machine three. As long as a machine
needs less than 1 billion ids over the life of the project, all should
be well. Problem solved?
