I'd want us to eventually aim for zero-copy speed for at least known immutable values (int, str, float, etc), immutable containers of immutable values (tuple, frozenset), and for types that support both publishing and consuming data via the PEP 3118 buffer protocol without making a copy.
For everything else I'd be fine with a starting point that was at least no slower than multiprocessing (which shouldn't be difficult, since we'll at least save the IPC overhead even if there are cases where communication between subinterpreters falls back to serialisation rather than doing something more CPU and memory efficient).
Makes sense. -eric
