The current API requires it. The main reason as you and Thiago note is 
that the API is asynchronous.

Well, it 'sort of' is - meaning, it should work. But if "transfer lots 
of data quickly" is your main priority, dbus isn't really the ideal or 
optimized IPC solution for that. Using dbus for large data would make 
sense more if you're using dbus anyway, and have some large data among 
your smaller calls, and it's not speed-critical.

You could always create an "out of band" large data transfer mechanism 
such as shared memory or a dedicated socket or a pipe, and use small 
dbus calls to coordinate it.
