This is the NeCTAR use case:

Oh yes, I forgot that landed during Havana. It had been done during the

Not just RPC, but RPC is a big one. Cells gives the ability to split up and
distribute work. If you divide hypervisors int

Hi Tim,
Can you comment on scalability more? Are you referring to just the RPC layer in
