Yeah. Ideally we'd be able to generate code for the existing (and
proposed binder) interfaces; however, I don't think that's actually
going to be possible since each one of the existing ones has its own
quirks already that we'd have to keep if we really were to convert.

Perhaps, with dbus, it'd be possible to add "dbus-new2" that would
follow some new tbd semantics, what would you think about that?

As far as binder is concerned, at the core it's just a binary message
passing - what kind of API do you (Christopher) envision on top? Did
you already start working on this? What kind of marshalling does this
use? Is it typically object-oriented, like dbus?

It seems to me that it would be possible to define, in some object-
oriented fashion, the API used, and then map that to the different
interfaces (socket/ctrl-iface, dbus, binder) in some build-time step.
