DBUS message formats

[quintesse at palacio-cristal.com]

Just curious, because I'm not really sure how dbus is normally used but
would it be (theoretically) possible in a future version to exchange the
binary protocol that is being used for another? Or is most of that code
statically included in some/most applications?

Cheers,
