If your application is designed to be synchronous, you can never be faster 
than a full roundtrip. How would a asynchronous version look like? This 
would be the part I'm most interested in, the true asynchronous case. On 
invocation, you would do the send only, i.e., the function returns 
immediately (perhaps even before doing the send). You would issue a 
completion handler with your request. 

perhaps

remote_function< void( int ) > m_func;

could be called

// synchronous case, throwing, blocking send/receive
m_func( 2 );

// asynchronous case, nonthrowing, fully async, completion handler
// result_type must be void
m_func( 2, some_handler )

or, something along the line of future semantics?

future<...> = m_func(2);
