When I initially read the description, I thought this could provide a drop-in runtime-linked shared library stub, but looking deeper in the docs and examples it appears there is at least some setup code required on the client side?

Can this log the RPC calls around the target C library? Or potentially even replay calls in isolation? The latter could be expensive for non-trivial programs (require saving all synchronized memory state?), but might be more viable with binary diffs of the shared state if the client side doesn't modify the synchronized memory too much.
