Sanjay already had a somewhat similar approach in managing the scheduling of concurrent RPCs, i.e., RPCs are enqueued, and a scheduler looks at the RPCs and figure out windowed batching order to optimize for the overall execution time (here the concurrent RPCs are interdependent).
That sounds like a slightly different problem. Unison looks like any function can transparently cross network boundaries versus the efficient scheduling and dispatching of concurrent rpcs.
