One CPU per process makes a lot more sense, especially now that we have so many specialized CPUs in our machines anyway.

Ye I got a feeling that shared processor time with strangers is not viable without specialized hardware.

I think it isn't viable with non-deterministic (in time) hardware behavior. This means dedicated caches, or no caches at all. Dedicated guaranteed memory speeds and latencies. Dedicated processing units. The untrusted code cannot be affected by other code, otherwise the other code leaks its usage patterns across.
