Conceptually, I think that he wants to serialize a boost::function<>. My
advice is "don't bother". I use shared_ptr<Command> for serializeable
polymorphic functions.

BTW, it is not necessary to serialize/marshal the function object in order
to pass it to a thread (pool), only IPC needs marshaling.
