Hello Vivek,

sorry for the late answer. Why don't you simply use the XML
introspection to generate your helper classes? It works like in the
echo example.

Maybe you've a special reason not to do it like in the echo example...?

we need to integrate dbus-cplusplus to use our existing event loop
mechanism (select based). And, we cannot afford to block over I/O (even
client-side calls).

We have managed to implement the required "eventloop integration"
classes.

However lately we noticed that, we cannot be completely asynchronous as
libdbus does synchronous stuff under the hood ('dbus_bus_add_match',
'dbus_bus_remove_match' for example). I am clueless as to how much this
is going to affect the rest of the application :-S. So, currently i'm
trying to profile and see whether we can bear with this or whether we'll
have to put dbus related stuff on a thread.
