By coincidence this is an active area of development for us right now. The original design used portals for every inter-module transfer. This forced portal overhead on modules in the same turf that were separately compiled and runtime-bound. For inter-turf calls it had the advantage that only exported entry points could be called. Signatures involve more than valid entry points however; argument lists must be as expected, and it must be verified that things like buffer arguments must be accessible to the caller before the callee uses the address. The current solution is NYF.
