(see all the other replies for why you might not want to do this,

You can use the dbus libraries and protocol on a point-to-point link
between two apps. This will gain you a common implementation with the
rest of your code and all the serialisation et al done by the libraries,
but it probably still has the same limitations of maximum message size
etc. You'll essentially end up passing a dbus address (unix:.... or
something) across the session bus and then connecting directly using

I don't know what the support for  this is like in bindings. I know
dbus-java can do it.
