This isn't what I quite had in mind for asynchronous client support.
Ideally, the service should be able supply return (out) parameters. I
don't want to block waiting for the results but instead have some sort
of callback invoked at a later time (e.g. like handling a signal). The
tricky part is probably registering the callback with the correct
signature for the response. Perhaps there would need to be some kind of
template trickery or use the facilities provided by libsigc++.
Regardless, your approach seems to only provide a "one-way" function
call. I truly want the results . . . I just don't want to block waiting
for them nor do I want to implement a service on the client-side that
exports a one-way "callback" method on which the service can return the
response. Is this possible? It appears that it's supported in the Glib
binding.
