Probably Rabin's work on beacons. It explored the results of assuming
a universally available oracle providing the same stream of random bits
to everyone. (If you think of the randomized Turing machine model
as a TM plus an oracle giving that machine a random bit stream, you
can think of this as a bunch of communicating TM's that get *the
same* random bit stream.)
