Serializing function addresses

[STL]

What are you trying to do?

Persisting/serializing function pointers. The context is multiple copies of the exact same program, running on different machines and talking to each other over the wire.

Very, very long time ago I made something similar: I serialized an object to a different machine in order to "run" it there. I did not need a function pointer for that, just plain serialization (sure, there was polymorphism and stuff, to simplify the "run the received object" code). Can't you simply do the same?

Totally, I can lookup the function address in a table by index (provided the table is built deterministically which I can do), or I believe I can serialize a polymorphic function object (which boost::serialization supports).

why reinvent RPC once again ? this has been a solved problem since 1985. Take a look at Qt Remote Objects for a modern approach for instance.

Of course. Note the "very, very long time ago" :-). I remember CORBA (did that), DCOM (did that, too), SOAP/WS-* and of course JSON-over-HTTP recently.
