(you can't send a D-Bus message to fire up the default "camera" application to take a picture, then fire up another message to the default "email" application sending the picture you just took as an attachment.)
Sure you can. Or at least you could, if you defined a well-known bus name and interface for the camera app and email app. DBus supports auto-activation, so it'll take care of starting the apps that register themselves as providing those bus names. That's all more or less what you have to do with intents, even.
