the very first objective of a remote invocation framework is to define a
single format for exposing the interface.
That has to be language independent and mapped to specific language in a
IMHO RPC, CORBA and other successful IPC technologies are inspired by
the principle of design by contract theorized here

a part of it)
Thinking at it now that it's time to make decisions it could make sense
