Not too concerned about this as a simple id association gives me what I
need for IPC.  I just prefix the associated id to the message.  Lots of
options for this, just need to pick one.

For a local call I'm hoping the mechanism will make the function call
implicit and then there will not be a need for a function<> or
shared_ptr <> indirection.

Thanks for your thoughts.  Appreciated.
